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).
