In the R tcltk example "List Box With A Scroll Bar" in List Boxes at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/

removal of "..." in 

scr <- tkscrollbar(tt, repeatinterval=5,
    command = function(...) tkyview(tl,...))

tl <- tklistbox(tt, height=4, selectmode="single",
    yscrollcommand=function(...) tkset(scr,...), 
    background="white")

results in message

"Error in function ()  : unused argument(s) ( ...)".

Why does the example work with "..." and not work when "..." are omitted,
or what process is occuring that requires "..."?

Thanks
