Sorry, I'm not with you.  I'm slow, and as I said, I don't
really grok environments.

Let's look at a toy example.  Suppose I want to create a function foo:


and assign n the value of 4, say, in the environment of foo.

Duncan Murdoch's solution was to create a function make.foo:

	make.foo <- function() {
		n <- 4
		foo <- function(x){x^n}

and then execute

	foo <- make.foo()

How would I go about accompishing the same (toy) task making use of the
local() function?
