I\'m trying to update packages on RGui (64-bit) using update.packages but I\'m getting the following message:

Warning in install.packages(update         


        

Answer 1

Uninstalling from C:\Program Files and re-installing to C:\R worked for me

[See mdsumner's comment and Windows FAQ found here]

"...Users of Vista/Windows 7/8/Server 2008/2012 installing for a single user using an account with administrator rights1 should consider installing into a non-system area (such as C:\R)"
