Re: [R] Setting hostname in the .Renvironment

They both use this as the default library for user installations:
'~/R/x86_64-pc-linux-gnu-library/2.13'
I would like to mod the .Renviron in such a way so
'~/R/hostname-1/x86_64-pc-linux-gnu-library/2.13'
'~/R/hostname-2/x86_64-pc-linux-gnu-library/2.13'
How can I modify my R_LIBS_USER in the .Renviron to match this? The
hostname would need to be dynamically set based on which computer I log
into, but I tried something like this:
R_LIBS_USER=~/lib/R/library/$HOSTNAME_%p_%a_%o_R%V
Depends on the shells you are using and where it is defined, but you
definitely need braces rather than quotes as in:
R_LIBS_USER=~/lib/R/library/${HOSTNAME}
and I have to
export HOSTNAME ${HOSTNAME}
at first on the machines I am using to have it accessible for R.
Best,

and R did not resolve the $HOSTNAME environment variable even though I can
(from bash) echo $HOSTNAME and it return the correct name.
Thoughts? Thanks!
