Hello,
I was looking at the R (installed on RHEL6) shell script and saw
R_HOME_DIR=/usr/lib64/R. Nowhere (and I could have got it wrong) does
it read in the environment value R_HOME_DIR. I have the need to rsync
the entire folder below /usr/lib64/R to another computer into another
directory location. Without changing the R shell script, how can i
force it read in R_HOME_DIR?
Or maybe i misunderstood the bash source?
(Note, i cannot recompile on target machine)
Cheers

1. I also realize Rscript will not work (i think path is hard coded in the
source)
Beginning of /usr/lib64/R/bin/R
R_HOME_DIR=/usr/lib64/R
if test "${R_HOME_DIR}" = "/usr/lib64/R"; then
case "linux-gnu" in
linux*)
run_arch=`uname -m`
case "$run_arch" in
x86_64|mips64|ppc64|powerpc64|sparc64|s390x)
libnn=lib64
libnn_fallback=lib
;;
*)
libnn=lib
libnn_fallback=lib64
;;
esac
if [ -x "/usr/${libnn}/R/bin/exec/R" ]; then
R_HOME_DIR=/usr/lib64/R
elif [ -x "/usr/${libnn_fallback}/R/bin/exec/R" ]; then
R_HOME_DIR=/usr/lib64/R
## else -- leave alone (might be a sub-arch)
fi
;;
esac
fi
