Configuring Java support
========================
To enable Java support, R needs to know where the JVM and the Java
libraries are located.

Running:

# export JAVA_HOME=${LOCALBASE}/jdk-1.8.0
# ${TRUEPREFIX}/bin/R CMD javareconf

as root, will update both ${TRUEPREFIX}/lib/R/etc/Makeconf and
${TRUEPREFIX}/lib/R/etc/ldpaths with the right settings.

Customizing package compilation
===============================
Make variables to be used by R packages compiling code at installation time
can be customized via ~/.R/Makevars
(https://cran.r-project.org/doc/manuals/r-release/R-admin.html#Customizing-package-compilation).
E.g., for using recent compilers (packages g++ and gcc) add

CC=egcc -std=gnu99
CXX=eg++
CXX11=eg++
CXX11STD=-std=c++11
CXX11PICFLAGS=-fpic
