The example for learning tcl/tk under R at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/OKtoplevel.html suggests running it from batch - but when I do, the window flashes by and the example ends. I'm under XP pro. Is there a workaround? Should I create a modal window instead so it persists? Thanks. -- View this message in context: http://www.nabble.com/tcl-tk-example-in-batch-tp18964294p18964294.html Sent from the R help mailing list archive at Nabble.com.
