I'm not enough of a Mac or Windows user to be in a position to answer that with a view towards all the possibilities R is used. WRT to ~/.R/ and ~/R/ I agree with your preference of using ~/.R/ as that has *already* been used for other configuration settings, and it seems awkward to have both side by side.
