I have been troubled by this problem for some time as well. (although boot
is a system library so your situation might be different). I can run 'R CMD
REMOVE' to remove a package but not from 'update.packages ()' inside R.
After some probing around, I found somehow there were extra symlinks under
the troublesome library directories, e.g.,
/Library/R/library/gee/gee -> /Library/R/library/gee
which can not be deleted by 'remove.packages()' whereas the command line has
no trouble.
I cleaned it up using
find /Library/R/library -type l -exec rm {} \;
Now everything seems fine (R 2.6.2) and there is no more such symlinks. Not
sure how it got there in the first place. (I ususally use 'install.packages
()'.)
