Insert your desired path in quotes assigned to the path_to_libraries variable:

path.expand("~")
.First <- function() {
  path_to_libraries <- "" 
  .libPaths(c(path_to_libraries, .libPaths()))
}

Remove the trailing slash. From ?.libPaths:

How paths new with a trailing slash are treated is OS-dependent. On a POSIX filesystem existing directories can usually be specified with a trailing slash: on Windows filepaths with a trailing slash (or backslash) are invalid and so will never be added to the library search path.
