Hi, all What I want to ask is "what is better gui between gwidgetsRGtk2 and gwidgetstcltk?" In my opinion, gwidgetsRgtk2 has more functionality for gui. For example , in importing image from file, Rgtk2 works with most of formats but tcltk only with gif and pnm. However, gwidgetstcltk is more lovely than Rgtk2. Is there a way to mix two of them or alternative? -- View this message in context: http://r.789695.n4.nabble.com/Choice-between-gwidgetsRGtk2-and-gwidgetstcltk-tp4528350p4528350.html Sent from the R help mailing list archive at Nabble.com.
