[R] formals or args question

Hello again, thank you again for all of your help. I am trying to get the arguments for a function, in a way that I can handle them. If I do args(fun), it doesnt really do what I want. If I use formals(fun) i get output like:

$a

$r

$s

Now, lthis is supposedly a list, but if i say formals(a)[[1]], I get nothing. I am just trying to get a vector with teh arguments of a function so I can loop over them.

ex; a<-function(p,r){p+r}

want: vector of c("p", "r")

The documentation for args and formals is quite confusing. Thanks again! ~Erithid
