Rscript - get rid of "WARNING: ignoring environment value of R_HOME"
i assume this is very old. but, with bash, etc.:
unset R_HOMEbefore running Rscript should do the trick. and, with csh, etc.:
unsetenv R_HOMEshould likewise work. since the R front-end script sets R_HOME (after complaining), i don't see any reason for leaving R_HOME set. (possibly i'm missing something.)
