R help - May 2012 - How do I modify sytem shell environment from within R?

Hi all,

Could you please tell me how do I modify the environment variable (as
below), from within R session?

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mypath
export LD_LIBRARY_PATH

Thanks a lot!

You don't, at least not for building libraries. Do it at the command line
before you invoke the R commands. If you are using Cygwin, then be sure to use
the Bash shell export command to set the variables.
