tdt() is a function within dgc.genetics.
dgc.genetics is a package written by David Clayton and available at

It consists of extensions to the genetics package.

I could always drop the text from the output of help(tdt) here. Would
that be acceptable ettiquete?

On the one hand my question is highly specific but on the other it
quite general..."How does one pass a whole batch of variable names to
a function that is not one of R base functions such as "mean")?"
