One way is to use a file ~/.Rprofile where you can have commands:

   ## add local library path
  .libPaths(c("~/R/Packages", .libPaths()))

which prepends the path to the default settings.

See help(Startup) for more alomgh tjese lines.

That is very dated. You may miss a number of recent / relevant packages.
