Hello, I have the TCl/Tk command "tkmessageBox(titel="",message="x",icon="question",type="okcancel")" in my R script. Now I want to perform some operation in relation to the user's choice, something like "if (okpressed) xxx else yyy" What values does this command give and how are they used? Thank you, Richard

res <- tkmessageBox(title = "test",message = "Continue?",
+ icon ="question", type = "okcancel") > if (tclvalue(res) == "ok") 1 else 2 Happy new year! Philippe Grosjean

Is it so hard to find out? Your tcl documentation will tell you what tk_messageBox returns, and as it is tcl string, you need to call tclvalue() on the value of tkmessageBox() to get an R character vector.

Why don't you test it yourself? library(tcltk) x <- tkmessageBox(title="",message="x",icon="question",type="okcancel") # press x or cancel x # <Tcl> ok or <Tcl> cancel To get back from this Tcl-thing to an R-string, use y <- tclvalue(x) Alberto Monteiro
