Hi Tal,

Three thoughts, not sure if any of them would pan out in your case.

1) Run R as an administrator
2) Shift your library location out of Program Files
3) just use install.packages("MASS"), the only downside is you'd have
to know the packages you wanted to update rather than just
update.packages() which will update everything you need at once for
you.

Best regards,

Josh
Hello all,

I am using R 2.13.0 with windows 7, after giving my user full privileges to
the R folder (as described
here<http://www.r-statistics.com/2011/04/how-to-upgrade-r-on-windows-7/>
).
This allows me to install new packages just fine.

However, when using update.packages(), to update existing packages, I keep
getting the following error (for example, when updating the MASS package):

package 'MASS' successfully unpacked and MD5 sums checked
Warning: unable to move temporary installation 'C:\Program
Files\R\R-2.13.0\library\file6cae3bcf\MASS' to 'C:\Program
Files\R\R-2.13.0\library\MASS'

Any suggestions on how to fix this?

Thanks,
Tal
