If you look at the help page for remove.packages(), it states that the second argument is taken to be the first element in .libPaths(). You have not told us what .libPaths() is returning and you should do so (even though it wasn't mentioned in the Posting Guide.) It seems possible that you set up an additonal library location which your new installation of R is "finding" but which is not the first item in the list of directories with library entries.
I have found that having two locations for libraries is an annoyance, and have removed all "user library" locations.

Let me second Prof. Ripley's suggestion that you do more reading of the /listinfo/ page and the Posting Guide.
