Hi, The following code, from the examples in ?TkWidgets , immediately crashes R 4.0.1 for Windows:
--------------------- snip -------------------- library("tcltk") tt <- tktoplevel() label.widget <- tklabel(tt, text = "Hello, World!") button.widget <- tkbutton(tt, text = "Push", command = function()cat("OW!\n")) tkpack(label.widget, button.widget) # geometry manager --------------------- snip -------------------- Session info (prior to the crash): --------------------- snip -------------------- > sessionInfo() R version 4.0.1 (2020-06-06) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 10 x64 (build 18363) Matrix products: default locale: [1] LC_COLLATE=English_United States.1252 [2] LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 [4] LC_NUMERIC=C [5] LC_TIME=English_United States.1252 attached base packages: [1] tcltk stats graphics grDevices utils datasets methods [8] base loaded via a namespace (and not attached): [1] compiler_4.0.1 tools_4.0.1 --------------------- snip -------------------- I observe this behaviour both in the Rgui and when I run R in a terminal. I think the problem is general to the use of the tcltk package.
