R help - Apr 2013 - Transferring R to another computer, R_HOME_DIR

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
Saptarshi

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

If you can't compile on the target machine, that indicates that you
wouldn't
have access to /usr/lib64/R anyway, so you need a different approach.

Fortunately, it's easy to compile into your home directory where you do have
write access.  The INSTALL file in the distributed tar.gz file shows 
you how to
compile where you want and what link you need to make it accessible.  Even
though the file is called INSTALL, it explains how it's not necessary to
install R in order to use it.

Well, to my understanding, you planned to rsync the original compiled
folder from one machine to somewhere on another machine, and work with it.
Then how about create a file link on the second machine for
"/usr/lib64/R"?
Or maybe I misunderstand your purpose?
