   There seems to be a spurious comma in your 'table' call.
(Also, I don't believe that's actually the precise error you
got -- it's good to cut and paste errors exactly, in case you
omit some important detail when transcribing)

> x <- 1:3
> y <- 2:4
> table(x,y,)
Error in table(x, y, ) : argument is missing, with no default
