You could have searched for R_LIBS in the manual (see below).

Set the environment variable R_LIBS in your commands windows/shell.
As the manual says:

   @quotation Note
   @code{R CMD check} and @code{R CMD build} run @R{} with
   @option{--vanilla}, so none of the user's startup files are read.  If
   you need @env{R_LIBS} set (to find packages in a non-standard library)
   you will need to set it in the environment.
   @end quotation
