HTTP_PROXY issues aside, if all you want to do is install Bioconductor,
simply download the latest bioconductor_xx.tar.gz and use R CMD
INSTALL.

Hi Henrik
Thanks for your help, I really do appreciate it.
If I follow your instructions, R returns the value
http://wwwcache.bbsrc.ac.uk:8080. That is good and it means that
indeed my http_proxy environment variable is set.
I have also added the lines
http_proxy=http://wwwcache.bbsrc.ac.uk:8080/
HTTP_PROXY=http://wwwcache.bbsrc.ac.uk:8080/
both to .Renviron in my home directory, and to /usr/lib/R/etc/Renviron
and /usr/lib/R/etc/Renviron.site.
All to no avail... R still doesn't try to connect through my proxy
server.
Please, I genuinely think this is a bug in R 1.7.1 on Suse Linux 8.1.
NOW, here is a little detail I have just discovered that PROVES my
proxy is working.
If I do:
update.packages(method="wget")
then everything works fine.... hmmmm, but I still have a problem as the
command I really want to run is :
source("http://wwwbioconductor.org/getBioC.R")
and source() does not accept an option 'method="wget"'....
SO... is there a way in R that I can set it up such that ALL internet
connections from within R use method="wget" ??
Thanks
Mick

Could it be that you have redefined the command R in your shell such
that the http_proxy environment variable is set in one and R is
running
in another? (This is just a wild guess and I am myself only running
WinXP.) What do you get if you do
% env http_proxy=http://wwwcache.bbsrc.ac.uk:8080/
% R
> Sys.getenv("http_proxy")
Also, have you considered setting http_proxy in ~/.Renviron (see
?.Renviron).
