I'm running R 1.8.1 on a Mac with OS X 10.3 (Panther). The edit.data.frame( ) function doesn't seem to work. A window opens but I can't figure out how to navigate around it or to edit or add data to the data frame. It works fine on MS Windows. Is this just a limitation of Raqua? Anyone know of plans to fix it? Rich Simon Richard Simon, D.Sc.
