[R] Cross compiling R

[Prof Brian Ripley]

Cross-building is not supported (building R is more than just compiling 
and needs a working R executable).

And (see the posting guide) this was not the right list for such a question.

It seems it generates the "R" executable for the Galileo board and also, it tries to run the executable to generate the base packages for R. Since the "R" executable (/home/vivek/Smart_Tracker/R/R-3.1.2/bin/exec/R) is not for x86 system but for Galileo board, it is not able to execute it and hence the error.  Can somebody guide me as how to cross compile R?
