Hi Michael,

Thanks for the reply and the research. The relevant file is

[djisgitt@prs1 R-2.3.0]$ ls -l $R_HOME/etc/Renviron
-rw-rw-r--    1 djisgitt djisgitt     1151 Jun  1 11:42
/home/djisgitt/R-2.3.0/etc/Renviron

so I don't see that as the problem.


I use R quite a lot, so I know the installation of R itself is good, but
this is the first time I have tried pl/R. Also, pgsql works, so I assume
there is something incorrect between pgsql and R. I just don't know what!

If you have any more suggestions, or need more information, let me know.
