[R] Can't save files from the Source pane of R Studio

[Parkhurst, David]

I�m just starting to learn and use R Studio in my Mac.  Now I find if I type lines in what I think is called the source pane, and use Save as from the menu, nothing gets saved.  That�s true if I add the extension .R or the extension .txt.  If I try reopen the file in an empty source pane, it�s empty.  And even if I open the file in a text editor, it�s blank.  How can I save my work from R Studio?
