E.g.

x <- 1

f <- function() {
  x <- 3
  g <- function() {
    x <<- 2
    return(NULL)
  }
  g()
  return(x)
}

print( c(f(), x) ) ## [1] 2 1

I'm kinda thinking there should be a section on namespaces and name resolution where this would fit nicely? I don't understand it yet though so I don't know when that's going to happen!

This is an exceptionally good post breaking all of that down: http://obeautifulcode.com/R/How-R-Searches-And-Finds-Stuff/ - it shares the similarly frustrated-with-R tone as well :)
