Hello all,
To set options in a package I'm putting together I'd like to write a
function like options, that is:
my.options <- function(...) {
# ...
}
Now I'd like to access the named arguments that were passed to my
funtion within that function. How does that work? formals() doesn't do
it, neither does args() or alist().
How is that done?
Thanks,
robert

One common way is dots <- list(...) and match.call() is also used. -- Brian D.
