In what way have you tried using data.frames? Without "commented,
minimal, self-contained, reproducible code" we are left guessing why you
are not succeeding. In stead of using a data.frame to return multiple
arguments, I would use a list. A short trvial example:
foo = function() {
return(list(foo = "bar", spam = 1, ham = c(1,2,3,4)))
}
dum = foo()
dum
dum[[1]]
dum[[2]]
dum[[3]]
