Littler Examples

Dirk Eddelbuettel

2015-10-28

Examples

We show and discuss a few of the files included in the inst/examples/ source directory of littler (which becomes the examples/ directory once installed). In a few cases we remove comment lines to keep things more concise on this page. We use $ to denote a shell (i.e. terminal) prompt.

Simple Command-line Use

littler can be used directly on the command-line just like, say, bc:

$ echo 'cat(pi^2,"\n")' | r
9.869604

Equivalently, commands that are to be evaluated can be given on the command-line

$ r -e 'cat(pi^2, "\n")'
9.869604

But unlike bc(1), GNU R has a vast number of statistical functions. For example, we can quickly compute a summary() and show a stem-and-leaf plot for file sizes in a given directory via

$ ls -l /boot | awk 'BEGIN {print "size"} !/^total/ {print $5}' | \
     r -de "print(summary(X[,1])); stem(X[,1])"

which produces something like

   Min. 1st Qu.  Median    Mean 3rd Qu.    Max.
     13     512  110100  486900  768400 4735000

  The decimal point is 6 digit(s) to the right of the |

   0 | 0000001122222279222
   2 | 79444
   4 | 71888
   6 | 
   8 | 
  10 | 
  12 | 
  14 | 8
  16 | 4
  18 | 
  20 | 333

As we saw in the preceding example, the program can also be shortened like using the new -d option which reads from stdin and assigns to a data.frame named X.

And, last but not least, this (somewhat unwieldy) expression can be stored in a helper script (where we now switch to using an explicit readLines() on stdin):

#!/usr/bin/env r

fsizes <- as.integer(readLines(file("stdin")))
print(summary(fsizes))
stem(fsizes)

(where calling #!/usr/bin/env is a trick from Python which allows one to forget whether r is installed in /usr/bin/r, /usr/local/bin/r, ~/bin/r, …).

CRAN package installation

Direct Installation

This is one of my favourite littler scripts which I use frequently to install packages off CRAN.

#!/usr/bin/env r

if (is.null(argv) | length(argv)<1) {
  cat("Usage: installr.r pkg1 [pkg2 pkg3 ...]\n")
  q()
}

## adjust as necessary, see help('download.packages')
repos <- "https://cran.rstudio.com" 

## this makes sense on Debian where no packages touch /usr/local
lib.loc <- "/usr/local/lib/R/site-library"

install.packages(argv, lib.loc, repos)

I invoke it all the time with one, two or more packages to install (or reinstall).

$ install.r digest RcppCNPy

It conveniently installs all dependencies, and uses the chosen target directory, all while keeping my R prompt (or prompts with multiple sessions) free to do other things.

With Command-Line Parsing

Thanks to the fabulous docopt package, we also have a variant with optional settings of repo and location. Below is the updated version from littler 0.2.1:

#!/usr/bin/env r
#
# A second example to install one or more packages, now with option parsing
#
# Copyright (C) 2011 - 2014  Dirk Eddelbuettel
# Copyright (C) 2014 - 2015  Carl Boettiger and Dirk Eddelbuettel
#
# Released under GPL (>= 2)

## load docopt package from CRAN
suppressMessages(library(docopt))       # we need docopt (>= 0.3) as on CRAN

## configuration for docopt
doc <- "Usage: install.r [-r REPO] [-l LIBLOC] [-h] [-d DEPS] [--error] [PACKAGES ...]

-r --repos REPO     repository to install from [default: http://cran.rstudio.com]
-l --libloc LIBLOC  location in which to install [default: /usr/local/lib/R/site-library]
-d --deps DEPS      Install suggested dependencies as well [default: NA]
-e --error          Throw error and halt instead of a warning [default: FALSE]
-h --help           show this help text"

## docopt parsing
opt <- docopt(doc)

if (opt$deps == "TRUE" || opt$deps == "FALSE") {
    opt$deps <- as.logical(opt$deps)
} else if (opt$deps == "NA") {
    opt$deps <- NA
}

## installation given selected options and arguments

if (opt$error) {
    withCallingHandlers(
        install.packages(pkgs  = opt$PACKAGES,
                         lib   = opt$libloc,
                         repos = opt$repos,
                         dependencies=opt$deps),
        warning = stop)

} else { 
    install.packages(pkgs  = opt$PACKAGES,
                     lib   = opt$libloc,
                     repos = opt$repos,
                     dependencies=opt$deps)
}

Installing From Sources

Starting with version 0.2.2, install.r and install2.r now recognise installable source files. So one can also do this:

$ install.r digest_0.6.8.tar.gz

and the local source file will the installed via a call to R CMD INSTALL.

Checking Packages

A related use case is to check packages via check.r. This script run R CMD check, but also installs package dependencies first as tests may have dependencies not yet satisfied on the test machine.

GitHub package installation

Installation directly from GitHub is also popular. Here is an example:

$ installGithub.r RcppCore/RcppEigen

Installing from github is supported via the following helper script:

#!/usr/bin/env r
#
# A simple example to install one or more packages from GitHub
#
# Copyright (C) 2014 - 2015  Carl Boettiger and Dirk Eddelbuettel
#
# Released under GPL (>= 2)

## load docopt and remotes (or devtools) from CRAN
suppressMessages(library(docopt))       # we need docopt (>= 0.3) as on CRAN
suppressMessages(library(remotes))      # can use devtools as a fallback

## configuration for docopt
doc <- "Usage: installGithub.r [-h] [-d DEPS] REPOS...

-d --deps DEPS      Install suggested dependencies as well? [default: NA]
-h --help           show this help text

where REPOS... is one or more GitHub repositories.

Examples:
  installGithub.r RcppCore/RcppEigen                     

installGithub.r is part of littler which brings 'r' to the command-line.
See http://dirk.eddelbuettel.com/code/littler.html for more information.
"

## docopt parsing
opt <- docopt(doc)
if (opt$deps == "TRUE" || opt$deps == "FALSE") {
    opt$deps <- as.logical(opt$deps)
} else if (opt$deps == "NA") {
    opt$deps <- NA
}

invisible(sapply(opt$REPOS, function(r) install_github(r, dependencies = opt$deps)))

CRAN package update

One of the scripts I use the most (interactively) updates installed packages:

#!/usr/bin/env r 
#
# a simple example to update packages in /usr/local/lib/R/site-library
# parameters are easily adjustable

## adjust as necessary, see help('download.packages')
repos <- "http://cran.rstudio.com" 

## this makes sense on Debian where no package touch /usr/local
lib.loc <- "/usr/local/lib/R/site-library"

## r use requires non-interactive use
update.packages(repos=repos, ask=FALSE, lib.loc=lib.loc)

As above, it has my preferred mirror and library location hard-wired.

Calling knitr

Here is another convenience script which knits a given file after testing the file actually exists.

#!/usr/bin/r
#
# Simple helper script for knitr
#
# Dirk Eddelbuettel, May 2013
#
# GPL-2 or later

if (is.null(argv)) {
    cat("Need an argument FILE.Rnw\n")
    q(status=-1)
}


file <- argv[1]
if (!file.exists(file)) {
    cat("File not found: ", file, "\n")
    q(status=-1)
}

require(knitr)
knit2pdf(file)

Running roxygen

Similar to the previous example, this one uses roxygen to extract documentation from R files – either in the current directory, or in the given directory or directories.

#!/usr/bin/r
#
# Simple helper script for roxygen2::roxygenize() 
#
# Dirk Eddelbuettel, August 2013
#
# GPL-2 or later

## load roxygen
library(roxygen2)

## check all command-line arguments (if any are given) for directory status
argv <- Filter(function(x) file.info(x)$is.dir, argv)

## loop over all argument, with fallback of the current directory, and
## call compileAttributes() on the given directory
sapply(ifelse(length(argv) > 0, argv, "."), FUN=roxygenize, roclets="rd")

Compiling Attributes

The next script can be used with Rcpp, and particularly is powerful Attributes feature, in order to auto-generate helper code. It is similar to the preceding script, but invokes compileAttributes() instead.

#!/usr/bin/r
#
# Simple helper script for compileAttributes() 
#
# Dirk Eddelbuettel, July 2014
#
# GPL-2 or later

## load Rcpp
suppressMessages(library(Rcpp))

## check all command-line arguments (if any are given) for directory status
argv <- Filter(function(x) file.info(x)$is.dir, argv)

## loop over all argument, with fallback of the current directory, and
## call compileAttributes() on the given directory
sapply(ifelse(length(argv) > 0, argv, "."), compileAttributes)

In a few cases we remove comment lines to keep things more concise on this page. We use `$` to denote a shell (_i.e._ terminal) prompt. ### Simple Command-line Use [littler](http://dirk.eddelbuettel.com/code/littler.html) can be used directly on the command-line just like, say, `bc`: ```bash $ echo 'cat(pi^2,"\n")' | r 9.869604 ``` Equivalently, commands that are to be evaluated can be given on the command-line ```bash $ r -e 'cat(pi^2, "\n")' 9.869604 ``` But unlike bc(1), GNU R has a vast number of statistical functions. For example, we can quickly compute a `summary()` and show a stem-and-leaf plot for file sizes in a given directory via ```bash $ ls -l /boot | awk 'BEGIN {print "size"} !/^total/ {print $5}' | \ r -de "print(summary(X[,1])); stem(X[,1])" ``` which produces something like ``` Min. 1st Qu. Median Mean 3rd Qu. Max. 13 512 110100 486900 768400 4735000 The decimal point is 6 digit(s) to the right of the | 0 | 0000001122222279222 2 | 79444 4 | 71888 6 | 8 | 10 | 12 | 14 | 8 16 | 4 18 | 20 | 333 ``` As we saw in the preceding example, the program can also be shortened like using the new `-d` option which reads from stdin and assigns to a `data.frame` named `X`. And, last but not least, this (somewhat unwieldy) expression can be stored in a helper script (where we now switch to using an explicit `readLines()` on `stdin`): ```r #!/usr/bin/env r fsizes <- as.integer(readLines(file("stdin"))) print(summary(fsizes)) stem(fsizes) ``` (where calling `#!/usr/bin/env` is a trick from Python which allows one to forget whether r is installed in `/usr/bin/r`, `/usr/local/bin/r`, `~/bin/r`, ...). ### CRAN package installation #### Direct Installation This is one of my favourite [littler](http://dirk.eddelbuettel.com/code/littler.html) scripts which I use frequently to install packages off [CRAN](https://cran.r-project.org). ```r #!/usr/bin/env r if (is.null(argv) | length(argv)<1) { cat("Usage: installr.r pkg1 [pkg2 pkg3 ...]\n") q() } ## adjust as necessary, see help('download.packages') repos <- "https://cran.rstudio.com" ## this makes sense on Debian where no packages touch /usr/local lib.loc <- "/usr/local/lib/R/site-library" install.packages(argv, lib.loc, repos) ``` I invoke it all the time with one, two or more packages to install (or reinstall). ```bash $ install.r digest RcppCNPy ``` It conveniently installs all dependencies, and uses the chosen target directory, all while keeping my R prompt (or prompts with multiple sessions) free to do other things. #### With Command-Line Parsing Thanks to the fabulous [docopt](https://github.com/edwindj/docopt.R) package, we also have a variant with optional settings of repo and location. Below is the updated version from [littler 0.2.1](http://dirk.eddelbuettel.com/blog/2014/10/19#littler-0.2.1): ```r #!/usr/bin/env r # # A second example to install one or more packages, now with option parsing # # Copyright (C) 2011 - 2014 Dirk Eddelbuettel # Copyright (C) 2014 - 2015 Carl Boettiger and Dirk Eddelbuettel # # Released under GPL (>= 2) ## load docopt package from CRAN suppressMessages(library(docopt)) # we need docopt (>= 0.3) as on CRAN ## configuration for docopt doc <- "Usage: install.r [-r REPO] [-l LIBLOC] [-h] [-d DEPS] [--error] [PACKAGES ...] -r --repos REPO repository to install from [default: http://cran.rstudio.com] -l --libloc LIBLOC location in which to install [default: /usr/local/lib/R/site-library] -d --deps DEPS Install suggested dependencies as well [default: NA] -e --error Throw error and halt instead of a warning [default: FALSE] -h --help show this help text" ## docopt parsing opt <- docopt(doc) if (opt$deps == "TRUE" || opt$deps == "FALSE") { opt$deps <- as.logical(opt$deps) } else if (opt$deps == "NA") { opt$deps <- NA } ## installation given selected options and arguments if (opt$error) { withCallingHandlers( install.packages(pkgs = opt$PACKAGES, lib = opt$libloc, repos = opt$repos, dependencies=opt$deps), warning = stop) } else { install.packages(pkgs = opt$PACKAGES, lib = opt$libloc, repos = opt$repos, dependencies=opt$deps) } ``` #### Installing From Sources Starting with version 0.2.2, `install.r` and `install2.r` now recognise installable source files. So one can also do this: ```bash $ install.r digest_0.6.8.tar.gz ``` and the local source file will the installed via a call to `R CMD INSTALL`. ### Checking Packages A related use case is to check packages via `check.r`. This script run `R CMD check`, but also installs package dependencies first as tests may have dependencies not yet satisfied on the test machine. ### GitHub package installation Installation directly from [GitHub](https://github.com) is also popular. Here is an example: ```bash $ installGithub.r RcppCore/RcppEigen ``` Installing from github is supported via the following helper script: ```r #!/usr/bin/env r # # A simple example to install one or more packages from GitHub # # Copyright (C) 2014 - 2015 Carl Boettiger and Dirk Eddelbuettel # # Released under GPL (>= 2) ## load docopt and remotes (or devtools) from CRAN suppressMessages(library(docopt)) # we need docopt (>= 0.3) as on CRAN suppressMessages(library(remotes)) # can use devtools as a fallback ## configuration for docopt doc <- "Usage: installGithub.r [-h] [-d DEPS] REPOS... -d --deps DEPS Install suggested dependencies as well? [default: NA] -h --help show this help text where REPOS... is one or more GitHub repositories. Examples: installGithub.r RcppCore/RcppEigen installGithub.r is part of littler which brings 'r' to the command-line. See http://dirk.eddelbuettel.com/code/littler.html for more information. " ## docopt parsing opt <- docopt(doc) if (opt$deps == "TRUE" || opt$deps == "FALSE") { opt$deps <- as.logical(opt$deps) } else if (opt$deps == "NA") { opt$deps <- NA } invisible(sapply(opt$REPOS, function(r) install_github(r, dependencies = opt$deps))) ``` ### CRAN package update One of the scripts I use the most (interactively) updates installed packages: ```r #!/usr/bin/env r # # a simple example to update packages in /usr/local/lib/R/site-library # parameters are easily adjustable ## adjust as necessary, see help('download.packages') repos <- "http://cran.rstudio.com" ## this makes sense on Debian where no package touch /usr/local lib.loc <- "/usr/local/lib/R/site-library" ## r use requires non-interactive use update.packages(repos=repos, ask=FALSE, lib.loc=lib.loc) ``` As above, it has my preferred mirror and library location hard-wired. ### Calling knitr Here is another convenience script which _knits_ a given file after testing the file actually exists. ```r #!/usr/bin/r # # Simple helper script for knitr # # Dirk Eddelbuettel, May 2013 # # GPL-2 or later if (is.null(argv)) { cat("Need an argument FILE.Rnw\n") q(status=-1) } file <- argv[1] if (!file.exists(file)) { cat("File not found: ", file, "\n") q(status=-1) } require(knitr) knit2pdf(file) ``` ### Running roxygen Similar to the previous example, this one uses roxygen to extract documentation from R files -- either in the current directory, or in the given directory or directories. ```r #!/usr/bin/r # # Simple helper script for roxygen2::roxygenize() # # Dirk Eddelbuettel, August 2013 # # GPL-2 or later ## load roxygen library(roxygen2) ## check all command-line arguments (if any are given) for directory status argv <- Filter(function(x) file.info(x)$is.dir, argv) ## loop over all argument, with fallback of the current directory, and ## call compileAttributes() on the given directory sapply(ifelse(length(argv) > 0, argv, "."), FUN=roxygenize, roclets="rd") ``` ### Compiling Attributes The next script can be used with [Rcpp](http://dirk.eddelbuettel.com/code/rcpp.html), and particularly is powerful _Attributes_ feature, in order to auto-generate helper code. It is similar to the preceding script, but invokes `compileAttributes()` instead. ```r #!/usr/bin/r # # Simple helper script for compileAttributes() # # Dirk Eddelbuettel, July 2014 # # GPL-2 or later ## load Rcpp suppressMessages(library(Rcpp)) ## check all command-line arguments (if any are given) for directory status argv <- Filter(function(x) file.info(x)$is.dir, argv) ## loop over all argument, with fallback of the current directory, and ## call compileAttributes() on the given directory sapply(ifelse(length(argv) > 0, argv, "."), compileAttributes) ``` littler/README.md0000644000175100001440000000572413050574324013241 0ustar hornikusers## littler [![Build Status](https://travis-ci.org/eddelbuettel/littler.png)](https://travis-ci.org/eddelbuettel/littler) [![License](http://img.shields.io/badge/license-GPL%20%28%3E=%202%29-brightgreen.svg?style=flat)](http://www.gnu.org/licenses/gpl-2.0.html) [![CRAN](http://www.r-pkg.org/badges/version/littler)](https://cran.r-project.org/package=littler) [![Downloads](http://cranlogs.r-pkg.org/badges/littler?color=brightgreen)](http://www.r-pkg.org/pkg/littler) A scripting and command-line front-end for GNU R permitting use of R in command-line contexts. ### So What Does it Do? ```r #!/usr/bin/env r ## for use in scripts other input | r ## for use in pipes r somefile.R ## for running files r -e 'expr' ## for evaluating expressions r --help ## to show a quick synopsis ``` See the [examples vignette](https://cran.r-project.org/package=littler/vignettes/littler-examples.html) for a full set of introductory examples. Also see the [examples/ directory](https://github.com/eddelbuettel/littler/tree/master/inst/examples), as well as maybe the [older tests directory](https://github.com/eddelbuettel/littler/tree/master/inst/script-tests) both of which are installed with the package. ### Installation #### Version 0.3.0 or later The package resides on the CRAN network and can be installed via ``` install.packages("littler") ``` #### Previous Versions up to 0.2.3 In general, simply running the script `bootstrap` will configure and build the executable. Running `make install` (possibly as `sudo make install`) will install the resulting binary. On Linux systems, ensure you have the `autotools-dev` package (or its equivalent on non-Debian/Ubuntu systems). On OS X, you may need to run `brew install automake autoconf` to get all the tools. #### Alternate Naming On some operating systems such as OS X, `r` is not different from `R`. As this risk confusing the main binary `R` for the R system with our smaller scripting frontend `r`, we suggest to consider running `configure --program-prefix="l"` which this leads to installation of a binary `lr` instead of `r`. #### Alternate R Version As littler uses autoconf its `AC_PATH_PROG()` macro to find `R`, one can simply adjust the `PATH` when calling `configure` (or, rather, `bootstrap`) to have another version of R used. For example, on a server with R-devel in this location, the following builds littler using this R-devel version: `PATH="/usr/local/lib/R-devel/bin/:$PATH" ./bootstrap`. ### More Information For more

hornikusersPackage: littler Type: Package Title: R at the Command-Line via 'r' Version: 0.3.2 Date: 2017-02-14 Author: Dirk Eddelbuettel and Jeff Horner Maintainer: Dirk Eddelbuettel Description: A scripting and command-line front-end is provided by 'r' (aka 'littler') as a lightweight binary wrapper around the GNU R language and environment for statistical computing and graphics. While R can be used in batch mode, the r binary adds full support for both 'shebang'-style scripting (i.e. using a hash-mark-exclamation-path expression as the first line in scripts) as well as command-line use in standard Unix pipelines. In other words, r provides the R language without the environment.

By embedding R, it permits four distinct ways to leverage the power of R at the shell prompt: scripting, filename execution, piping and direct expression evaluation. } \details{ The \code{r} front-end was written with four distinct usage modes in mind. First, it allow to write so-called \sQuote{shebang} scripts starting with \code{#!/usr/bin/env r}. These \sQuote{shebang} scripts are perfectly suited for automation and execution via e.g. via \code{cron}. Second, we can use \code{r somefile.R} to quickly execute the name R source file. This is useful as \code{r} is both easy to type---and quicker to start that either \code{R} itself, or its scripting tool \code{Rscript}, while still loading the \code{methods} package. Third, \code{r} can be used in \sQuote{pipes} which are very common in Unix. A simple and trivial example is \code{echo 'cat(2+2)' | r} illustrating that the standard output of one program can be used as the standard input of another program. Fourth, \code{r} can be used as a calculator by supplying expressions after the \code{-e} or \code{--eval} options. } \value{ Common with other shell tools and programs, \code{r} returns its exit code where a value of zero indicates success. } \note{ On OS X one may have to link the binary to, say, \code{lr} instead. As OS X insists that files named \code{R} and \code{r} are the same, we cannot use the latter. } \author{ Jeff Horner and Dirk Eddelbuettel wrote \code{littler} from 2006 to today, with contributions from several others. Dirk Eddelbuettel \email{edd@debian.org} is the maintainer. } \examples{ \dontrun{ #!/usr/bin/env r ## for use in scripts other input | r ## for use in pipes r somefile.R ## for running files r -e 'expr' ## for evaluating expressions r --help ## to show a quick synopsis } } \keyword{package} littler/man/r.Rd0000644000175100001440000000116112751400225013247 0ustar hornikusers% Generated by roxygen2: do not edit by hand % Please edit documentation in R/test.R \name{r} \alias{r} \title{Return Path to \code{r} Binary} \usage{ r(usecat = FALSE) } \arguments{ \item{usecat}{Optional toggle to request output to stdout (useful in Makefiles)} } \value{ The path is returned as character variable.
