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 to have a list in my workspace called win in which one of the components was called env. I suggest that this either be changed or documented. I spent quite a large amount of time until I realized what was going on. ______________________________________________ R-devel@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
