Can you _please stop abusing the bug tracking system_ by asking these
beginner questions?

This is answered, inter alia, in

     help(install.packages)   # telling you about option("repos")
     help(options)	      # telling you about the repos option
     help(Startup)	      # telling you about R's inits

as well as the different manuals.

Also, see one of the emails I just sent you for the concrete example:

     edd at joe:~$ cat .Rprofile
     # as in AER by Zeileis and Kleiber
     options(prompt="R> ", digits=4, show.signif.stars=FALSE)
     options("repos"="http://cran.us.r-project.org")    ## US mirror

Lastly, *please* switch to r-sig-debian for help with your Debian / Ubuntu
system and stop abusing the r-devel list and the bug tracker.
