Galton’s quincunx in R

December 13, 2009

(This article was first published on Gregor Gorjanc (gg), and kindly contributed to R-bloggers)

Andrej Blejec has a very nice R demo of Galton’s quincunx (link1, link2). It is a bit tedious to copy the code from PDF to R console, but it is worth the effort as the demo simulation clearly shows the nature of quincunx. After a bit of search I also found a similar function quincunx in the animation R package by Yihui Xi.
