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.

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
