Note that the R version of this buildpack is 3.2.1.
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.
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 hosted on AWS S3 at s3://heroku-buildpack-r.
See the heroku-buildpack-r-build repository for building the R binaries yourself.
Optionally, the R version and buildpack version can be configured by providing a
.r-buildpack-version file in the root directory.
These files should contain 1 line of text containing the respective version. See alternate-versions for an example.
The following versions are available:R-2.15.1-binaries-20131211-0028.tar.gz 3.0.2 20140218-0019 R-3.0.2-binaries-20140218-0019.tar.gz 3.1.0 20141127-0021 R-3.1.0-binaries-20141127-0021.tar.gz 3.1.2 20150301-1046 R-3.1.2-binaries-20150301-1046.tar.gz

Due to the size of the R runtime, the slug size on Heroku, without any additional packages or program code, is approximately 90Mb.
If additional R packages are installed by the
init.r script then the slug size will increase.
