This is a CloudFoundry buildpack for applications which use R for statistical computing and CRAN for R packages.
It's a fork from the R buildpack for Heroku.
R is ‘GNU S’, a freely available language and environment for statistical computing and graphics which provides a wide variety of statistical and graphical techniques: linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, etc. Please consult the R project homepage for further information.
CRAN is a network of ftp and web servers around the world that store identical, up-to-date, versions of code and documentation for R.
Example usage (replace <app_name> with the name of your app):
$ ls
init.r prog1.r prog2.r ...
$ cf push <app_name> -b http://github.com/alexkago/cf-buildpack-r.git
...
-----> R successfully installed
The buildpack will detect your app makes use of R if it has the init.r file in the root.
The R runtime is vendored into your slug, and includes the gcc compiler for fortran support.
During the slug compilation process, the init.r R file is executed. Put code in this file to install any packages you may require.
See the Installing-packages for details. The
list of available packages can be found at http://cran.r-project.org.
# Example `init.r` file
install.packages("nlme", dependencies = TRUE)
R packages can also be included in your project source and installed when the init.r file is executed.
install.packages("optional-path-to-packages/local-r-package-file.tar.gz", repos=NULL, type="source")
The binaries used by the buildpack are for R 3.0.1, and are hosted on https://s3.amazonaws.com/r-buildpack/R-3.1.0-binaries-20140629-2201.tar.gz
See the guide for building the R binaries yourself.
Due to the size of the R runtime, the slug size on Cloud Foundry, without any additional packages or program code, is approximately 98Mb.
If additional R packages are installed by the init.r script then the slug size will increase.
