If you want to change your library path permanently (without calling .libPath() every time when entering in R, this works for me:

1. create .Rprofile under your home directory. (~/.Rprofile)

2. type .libPaths(c( .libPaths(), "your new path" )) in .Rprofile file, save.

3. open R (any directory) and check, just type .libPaths(), you can find your libaray path is updated!
