Error message library()

"BTW: an ever more intuitive solution (IMHO) would be to auto-complete package names in library( ... Deepayan?;)  That is non-intrusive and in line with the general use of R." (Simon)

This is indeed a long wanted feature and to my surprise it actually already exists!!! (seems that Deepayan did not tell anybody about it ;) )
The help page ?completion in the utils package explains how to enable it:

utils::rc.settings(ipck=TRUE)

It simply worked on my Ubuntu box -- and directly went in my .Rprofile :)
Hope this helps.
