cformat switch: R
Similar to T (checkbox) but has the additional behavior of automatically clearing any other radio buttons in the same group when one of them is set. Thus a group of radio buttons may serve as a way of inputting a "one of" choice. See sample program XTRA6.
By default, all of the radio buttons on a row are in the same group, whether contiguous or not. To define multiple groups of radio buttons (or a vertical group), see the "Group" option in Advanced Coldef Options.
The XTRA6 sample program illustrates radio buttons with cell colors.
See cformat code r for non-editable radio button.
