I am trying to understand the concept of lexical scope in "An Introduction
to R" by the R Core development team.
I'd appreciate it if someone would explain why the following example does
not work:
q <- function(y) {x + y}; w <- function(x){q(x)}; w(2);
According to the discussion of Scope on page 46, it seems to me that R
will interpret the free variable x in q as the parameter x in w, and so
will
give w(2) = 2+2.
