[R] tcltk: click and return table cell index

I'm struggling mightily with what should be a simple task...when a user
clicks on a cell in a tcltk table widget, I need to know which cell was

One idea that gives a cryptic error:
tkbind(table1, "<Button-1>", function(x, y){
  tcl(table1, "index", x, y)

# x, y give pixel coordinates; "index" should give cell coordinates, but
format must be correct

I get an error message:

wrong # args: should be ".25.1 index <index> ?row|col?".

To which I respond, "Yes, I know I have the format wrong, but how can I
make sense of THAT?"

Does anyone know a simple fix?

Much appreciated!
