Matrix Algebra in R: Resources, Videos, Textbooks

I noticed how John Myles White has posted a useful overview of Matrix Algebra in R. This post lists a couple of other resources that are available on the Internet on the topic, including R resources, online video courses, and online textbooks.

• Quick-R has a basic crib sheet of matrix algebra functions in R
• William Revelle posted some material on matrix algebra to accompany a course on SEM. A related more comprehensive ebook on psychometric theory is also available.
• Søren Højsgaard has a set of notes on R and matrix algebra.
• James H. Steiger also has a basic introduction to matrix algebra in R

Matrix Algebra Resources

• Videos: I've previously posted lists of online video mathematics courses. Gilbert Strang has one on linear algebra.
• Textbooks: Robert Beezer's free textbook on linear algebra; SOS Mathematics
