[R] Unused Arguments Error Even Though I'm Using Them?

[Christopher Simons]

Greetings,

I am running into an error I can't seem to get past; something tells
me I am making an obvious mistake as I am new to R, but everything
looks fine to me.  Basically, I'm getting the message "unused
arguments" even though my arguments are all being used.  I have posted
my code at the following URL:

Thanks for any help,
