[R] update packages with R on Vista: error

[Stefan Grosse]

Thanks for pointing at this. But you know, the user is writable. R is
installing Packages in /Documents/R/win-library which works fine so I
find it absolutely naturally that update should work as well. Especially
since when I install the packages it gets the latest version, library
loads this latest version but update still does want to update this
latest package with the package I already installed and fails ...

In my opinion the update on windows is simply buggy.

I think one should definitely not turn UAC off. ( its a good security
feature). Btw. MikTeX 2.6 is able to deal with UAC - I can update my
latex packages without any problems even though they are in the Program
File directory (and also on-the-fly installation does work) ...
