Errata: Functional Programming in R
The Structure of a Recursive Function, page 32:
“Here I am assuming that is an integer…” should be “Here I am assuming that n is an integer…”
Nested Functions and Scopes, page 53ff.
The code defines function g as
g <- function(y) x + y but in the environment chains g is defined as
g <- function(y) x + 1; that should also be
g <- function(y) x + y.
