Sebastian, Try James Wettenhall's R TclTk Examples at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ In particular, radio buttons are described here and check boxes are also there. Radio buttons in R TclTk at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/radiobuttons.html The following example illustrates the use of radio buttons in a tk toplevel window. The choice of radiobutton is mapped to a Tcl variable called rbValue, which is initialized to "oranges", which is the value of the second radio button (i.e. initially, the second radio button will be selected). The OnOK function triggered by the OK button captures the value of the Tcl variable mapped to the radiobuttons (rbValue) before destroying the window. Then it displays an appropriate message box depending on the choice of radiobutton. require(tcltk) tt <- tktoplevel() rb1 <- tkradiobutton(tt) rb2 <- tkradiobutton(tt) rbValue <- tclVar("oranges") tkconfigure(rb1,variable=rbValue,value="apples") tkconfigure(rb2,variable=rbValue,value="oranges") tkgrid(tklabel(tt,text="Which do you prefer?")) tkgrid(tklabel(tt,text="Apples "),rb1) tkgrid(tklabel(tt,text="Oranges "),rb2) OnOK <- function() { rbVal <- as.character(tclvalue(rbValue)) tkdestroy(tt) if (rbVal=="apples") tkmessageBox(message="Good choice! An apple a day keeps the doctor away!") if (rbVal=="oranges") tkmessageBox(message="Good choice! Oranges are full of Vitamin C!") } OK.but <- tkbutton(tt,text="OK",command=OnOK) tkgrid(OK.but) tkfocus(tt) There are lots of other examples as well, cheers, Keith Satterley, Bioinformatics and Genetics, The Walter and Eliza Hall Institute of Medical Research, Melbourne, Victoria, Australia.
