Dear R I installed R2.11.1 on Windows XP and because of University access control I set the Cran and web passwords in the Rprofile.site file # set a CRAN mirror local({r <- getOption("repos") r["CRAN"] <- "http://cran.ru.ac.za/" options(repos=r)}) Sys.setenv(http_proxy="http://prheeder:*****:xxxxx.up.ac.za:8080") I connected and downloaded packages without a problem. Due to problems with R I had R uninstalled and the re-installed. Now using exactly the same Rprofile file as before I cannot get access to the Cran site. I get the error message: Warning: unable to access index for repository http://cran.ru.ac.za/bin/windows/contrib/2.11 Warning: unable to access index for repository http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.11 Error in install.packages(NULL, .libPaths()[1L], dependencies = NA, type = type) : no packages were specified I have another computer accessing the web with R on the same network without any problem. It seems the unistall and re-install created some kind of a problem. Any advice? Paul
