Hi, I'm running the latest version of R on a linux box. plot() does produce a grahpics window. But is it "normal" for that window to not respond to a left or right mouse click? What I'm really trying to do is the save the graphics to a postscript file, but postscript() produces an "empty postscript file". Thanks, Caren -- http://www.nhn.ou.edu/~marzban
