Dear Bernhard, Peter, and Brian, Thanks, Peter, for the suggestion. If you're right then the problem is with tcltk more generally and not directly with the Rcmdr package.
Brian: That's easily checked and might clarify what's going on: Load the tcltk package via library(tcltk), and then try the following example from ?TkWidgetcmds: ------------ snip -------------- tt <- tktoplevel() tkpack(txt.w <- tktext(tt)) tkinsert(txt.w, "0.0", "plot(1:10)") eval.txt <- function() eval(parse(text = tclvalue(tkget(txt.w, "0.0", "end")))) tkpack(but.w <- tkbutton(tt, text = "Submit", command = eval.txt)) ## Try pressing the button, edit the text and when finished: tkdestroy(tt) ------------ snip -------------- Best, John > -----Original Message----- > From: Pfaff, Bernhard Dr. <bernhard.pf...@invesco.com> > Sent: Wednesday, March 11, 2020 9:18 AM > To: Peter Dalgaard <pda...@gmail.com>; Fox, John <j...@mcmaster.ca> > Cc: r-help@r-project.org > Subject: AW: Re: [R] Problem launching Rcmdr > > Good catch, Peter; Cylance might be the culprit - at least I encountered > problems by compiling C++ sources and/or building packages with interfaced > routines and here a memory checker kicked in. > Maybe something akin is happening by launching Rcmdr (tcl/tk)? > > -----Ursprüngliche Nachricht----- > Von: R-help <r-help-boun...@r-project.org> Im Auftrag von Peter Dalgaard > Gesendet: Mittwoch, 11.
