Could someone tell me how to embed windows in a text box using "tkcreate" command of R tcltk package? I tried the following and was not successful; base <- tktoplevel() text <- tktext(base, width = 30, height = 10) tkpack(text) button <- tkbutton(text, text = "try") tkcreate(text, "window", "end", window = button) Thanks.
