Re: [R] Transferring R to another computer, R_HOME_DIR

2013-04-26 Thread 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.

Or maybe I misunderstand your purpose?


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

No, compiled it when it is compiled.

[R] 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

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.
