Hi, I am trying to run some simple tktcl code....
## in a file called test.R require(tcltk) tt <- tktoplevel() OK.but <- tkbutton(tt,text="OK",command=function()tkdestroy(tt)) tkgrid(OK.but) tkfocus(tt) Using a batch file with the command Rterm < test.R > testOutput.Rout --slave The GUI pops up but then disappears. The results in the test.Output.Routfile are > # Load the tcltk package > require(tcltk) Loading required package: tcltk [1] TRUE > > # Create a new toplevel window > tt <- tktoplevel() > > # Create a button whose function (command) is to destroy the window > OK.but <- tkbutton(tt,text="OK",command=function()tkdestroy(tt)) > > # Place the button on the window, using the grid manager. > tkgrid(OK.but) <Tcl> > tkfocus(tt) <Tcl> > Does anyone know how to make the GUI stay open?
