Something is not right there (^^^^) is this exactly what you typed?
You should not send questions about contributed packages to the list ---
as detailed in the posting guide. Without seeing Table1a and Table0a, it
is hard to say why this is failing - I suspect something about the
structure of the two data frames is throwing the function off.
If you can, send me that data ***off-list*** and I will take a look for
you, but as I'm teaching all day tomorrow, it won't happen till after
the weekend now.
