[R] R won't connect to the internet on Linux!

[michael watson (IAH-C)]

OK, I really am struggling with this one!  Forgive me if I am being stupid....

I am running R 1.7.1 on Suse Linux 8.1.  I connect to the internet through a proxy so I have:

IAHC-LINUX03:~ # echo $http_proxy
wwwcache.bbsrc.ac.uk:8080
IAHC-LINUX03:~ # echo $HTTP_PROXY
wwwcache.bbsrc.ac.uk:8080

just in case ;-)

SO, i go into R and I get:

> source("http://www.bioconductor.org/getBioC.R")
unable to connect to 'www.bioconductor.org' on port 80.
Error in file(file, "r") : cannot open URL `http://www.bioconductor.org/getBioC.R'

OK so is R just not picking up my proxy setting?  It seems to be trying port 80 on something, and I have specifically set it to port 8080 in my environment variables.  As far as I can see I have followed the reference manual suggestion, so does anyone else have one?

Thanks
Mick
