Duncan:
Indeed, adding the function names to the NAMESPACE file (in the form:
export(functionName)) solved the problem,
and the args() function displays the function argument lists.
Thanks,
Rick Reeves

Is the function visible (e.g., if you type the name of the function,
does it print)? I would guess not: I think you have a NAMESPACE
file, and you haven't listed this function in it.
If you don't have a NAMESPACE file, or you do have one and you list
this function, then I think you need to be more forthcoming with
accurate information. When I type args(function), I don't get the
error you get, since "function" is a reserved word:
> args(function)
Error: unexpected ')' in "args(function)"
