[R] Transferring R to another computer, R_HOME_DIR

[Prof Brian Ripley]

This is really an R-devel topic: it is not about using R.

R is usually (but not always) built so that everything except Rscript is 
relocatable by editing the 'R' script (and R_HOME and R_HOME_DIR are 
ignored in the environment, intentionally).

So you could edit the script, but not having Rscript working is a 
limitation.

Having said that, not all packages play by the same rules and e.g. some 
use -rpath to hardcode paths in package DSOs.

If you have write permission there, you could install the R RPM.

No, compiled it when it is compiled.
