You probably want mylist[[i]] = function(...)
in your loop. Similarly, when you want them again later, you need to use double square brackets. I once heard a useful metaphor for understanding the difference between [ and [[ when it comes to lists. If x (a list) is a train, then x[2] is the second car of that train, while x[[2]] are the contents of that second car. That's why things like, x[1:3] are well defined (the sublist containing elements 1 through 3) while x[[1:3]] are not.
