Thanks Peter and Dan for your replies. After learning a bit more about tcltk and environments etc. I have replaced Try(n <- evalq(TclVarCount <- TclVarCount + 1, .TkRoot$env)) with Try(n <- .TkRoot$env$TclVarCount <- .TkRoot$env$TclVarCount +1L) as you suggest. It now works for both R-3.1.1 and R-3.1.2+ (My understanding is that the Try function is there to put a GUI box around the error messages.) I shall update affylmGUI versions accordingly soon....

Seems unlikely that that particular bug is involved. I seem to recall some change related to inadvertent variable capture in .TkRoot$env (?). At any rate, we currently have > parent.env(.TkRoot$env) <environment: R_EmptyEnv> which used to be > parent.env(.TkRoot$env) <environment: R_GlobalEnv> as a result, this won't work any more because R_EmptyEnv has no operators and functions in it: > evalq(x &l...

The following gives an error message: library(tcltk) win <- list(env="A") tt <- tktoplevel() but <- tkbutton(tt, text="X", command=expression(tkdestroy(tt))) tkgrid(but) however, if one comments out the win line (and removes the win variable) then it works. It seems that tcltk is making use of a variable called win with a component name of env and I just happened

Hi all, New wxRuby event handling offers the choice between using blocks or methods seamlessly and easily. This is great respectively for simple app and more complex app. Nevertheless, currently the creation of an application, a frame, or a dialog is very tedious for simple app : - you need to create a subclass of Wx::App, Wx::Frame ... - you need to put the initialization code in the initialize
