[R] Error Downloading Matrix Package

[Prof Brian Ripley]

Possible answers:

1) You do not have permission to remove the package from its previous 
location.

2) Windows mistakenly thinks that some file in the package is still open.

Try deleting the directory from Windows Explorer.  If 2) you may have to 
log out or reboot Windows before you can do so.

BTW, my Windows setup updated successfully this morning, so this is indeed 
a local problem.
