What is R?
The definition from The R-Project website says that R is:
" R is a language and environment for statistical computing and graphics."
R is a GNU project, very similar to the S language developed by Bell Laboratories.
This language is heavily used in research as it provides a lot of statistical and graphical tools. It is also a well developed language for data manipulation.

Spec Templates for R packages
There are two types of R packages: arch-specific and noarch.

R2spec
R2spec is an excellent little tool to assist in creating Fedora-compliant packages for R libraries. Using it as a starting point is recommended (but certainly not mandated). More information here : https://fedorahosted.org/r2spec/
R packaging tips
Naming of R packages
Packages of R modules (thus they rely on R as a parent) have their own naming scheme. They should take into account the upstream name of the R module. This makes a package name format of R-$NAME
. When in doubt, use the name of the module that you type to import it in R.
'''Examples: '''
R-mAr (R module named mAr) R-RScaLAPACK (R module named RScaLAPACK) R-waveslim (R module named waveslim)
R version
Many R packages contain '-' in their version. Usually, the versioning used is a sequence of at least two (and usually three) non-negative integers separated by single '.' or '-' characters.
To be consistent with the versioning system used in Fedora, you should simply replace dashes with dots.
Example:
Upstream tarball: Rfoo-0.5-8.tar.gz Fedora Version: 0.5.8
Empty %build section
Unlike normal Fedora packages, there is normally no separate %build
actions (e.g. %configure
)that need to be taken for an R package. However, it is important that all R module packages include an empty %build section, as shown in the spec templates.
Installing the R addon bits
Instead of calling make install, to install the R addon components, you need to run R CMD INSTALL -l $RPM_BUILD_ROOT%{_datadir}/R/library %{packname}
(noarch) or R CMD INSTALL -l $RPM_BUILD_ROOT%{_libdir}/R/library %{packname}
(arch-specific). Proper %install
sections for Fedora R packages are demonstrated in the spec templates.
Deleting the R.css file
Most R addon modules generate a new R.css file, but it would conflict with the master R.css file, included in the main R package. You must delete this file, and do not include it in your package.
Cleaning the R directory of binaries
It is important to clean the R directory of binary files (*.o *.so) before running R CMD CHECK. Otherwise, the CHECK command will throw a warning about finding binaries in the source dir. This is accomplished by running (in %install):
test -d %{packname}/src && (cd %{packname}/src; rm -f *.o *.so)
This is demonstrated in the spec templates.
Running %check
Most (if not all) R addon modules come with a built-in check. This can be triggered by running R CMD check
. In Fedora, the check should be run in the %check
section. Here is an example %check
section for a Fedora R package:
%check %{_bindir}/R CMD check %{packname}
Note that frequently, R packages have circular dependency loops when running R CMD check
. If you hit such a case, you can comment out the check to break the dependency loop, and leave a comment explaining the circular dependency problem.
Documentation files
The R CMD INSTALL
operation will install all of the files, including documentation files. The doc, html and NEWS files/directories need to be marked as %doc
.
Note that other files, such as DESCRIPTION, INDEX, NAMESPACE, and help/ are not %doc
, since proper R functionality depends on their presence. Be careful not to duplicate %doc
files in the package, the spec templates provide good examples on how to package the R addon files without duplications.
Optimization flags
R packages inherit their optimization flags from the main R package, which stores them in %{_libdir}/R/etc/Makeconf
. The design of R is such that all R addon library modules use the same optimization flags that the main R package was built with. Accordingly, this is why R addon packages do not pass $RPM_OPT_FLAGS
. Also, there is no simple way to pass special optimization flags to R CMD INSTALL
.
