[R] How to modify the body of a function?

[William Dunlap]

This is a real hack, but you can redefine return in your function:
> f <- function() {
+     return("early return")
+     "last value in function"
+ }
> f()
[1] "early return"
> f <- function() {
+     return <- function(x)x
+     return("early return")
+     "last value in function"
+ }
> f()
[1] "last value in function"

IMO, well written functions do not have return statements in them.  They
are the equivalent of goto statements.
