I've run into this problem on nearly every new machine I've touched in the
past year. Here is a solution that has consistently worked for me in
Windows 7 & 10:
1. Use .libPaths() to find where packages are being stored.
2. To change this path: Control Panel > search “View advanced system
settings” > Environment Variables *button *>
a. *Edit* current R_LIBS_USER to new file path (you might have to
create this - I did just yesterday)
b. *New* R_LIBS_USER with desired file path
3. Restart machine.
