Errata: Functional Programming in R

Chapter 2

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…”

Figures 2-1 and 2-2 in second edition (Functional programming in R4)

Chapter 3

Nested Functions and Scopes, page 53ff.
