[R] tcltk difficulties
Friends: I have a tcltk widget for inputting constants and other values that are needed by subsequent R functions. My widget works well. I have an OnOK function that does what I had hoped it would. Among other input items the widget also uses 6 radio buttons to select one of 6 choices. It functions as it should. Here is the problem: I would like one of the buttons to be the default and to be switched on when the widget is created so that the user will have some guidance. (Currently all 6 buttons are blank until one is selected.) I can't handle the job. I have Welch and Jones _Practical Programming in Tcl and Tk_ but would appreciate any help from fellow R users. Many thanks. Charles Annis, P.E.

Thank you, Peter. The code provides a great example of packing the widget nicely too. Charles Annis, P.E.
