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

Greetings:
I have check the 'Building R Extensions' manual and can find no advice
on this issue,
so I am asking --
I have created an R package consisting entirely of R source code, and
created an installer
using the R CMD build / R CMD check commands. The package installs
correctly, using
R CMD install, and the .Rd files for each function (one function per .R
/ .Rd file) are visible
using the '?function' command. However, the 'args(function)' command
does not list the
function prototype; instead generating the error:
Error in args(function) : object function not found.
Question: If it is possible, what changes do I make to my package and
install process to get
args() to display the function prototype(s) for the functions in my
local package?
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)
