R is special case, as we need to manage R libraries.
Package RR contains all R stuff compiled in the installation environment. Package RRlibUtils contains scripts used to install and upgrade R libraries.
Package RR provides executables RR and RRscript — the only difference between these executables and standard R and Rscript is that execution is performed in environment with special directories containing available libraries.
Packages RR and RRlibUtils may be installed in any order, but both packages must be installed in order to make RR usable.
Required system packages
The following system packages must be installed (using yum):
redhat-lsb-core
libtiff-devel
libcurl-devel
R library versions
For R version M.N.x, libraries are installed in directories $SOFTWARE_DIR/RRlib/M.N/YYY-MM-DD, where YYYY-MM-DD is the date when libraries were installed/updated.
