Change R default library path using .libPaths in Rprofile.site fails to work

Question

I am running R on Windows, not as an administrator. When I install a package, the following command doesn\'t work:

> install.packages(\"zoo\")
Installing          


        

Answer 1

If your default package library has been changed after installing a new version of R or by any other means, you can append both the libraries to use all the packages with the help of the commands below. Get the existing library path :

.libPaths()

Now,set the existing and the old path :

.libPaths(c(.libPaths(), "~/yourOldPath"))

Hope it helps.
