I am trying to obtain the lenght of all the formals in r functions in order to know which.max in the list created. I am a Psychologist not a programer

Question

This is the code for creating the list:

objs <- mget(ls("package:base"), inherits = TRUE)
funs <- Filter(is.function, objs)

I have tried this:

form_list <- for(i in names(funs)) {
        formals(i)
}

It produces an empty object. Then I have tried

form_list <- sapply(names(funs), formals)
longer_args <- sapply(form_list, length)
longest_args <- which.max(longer_args)
long_funct <- funs[961]

evaluates:

$scan
funs_elem <- length(formals(scan))

 funs_elem
[1] 22

It is there a shorter way to the answer? Excuse my English.
