One of my more popular posts is A brief introduction to “apply” in R. Come August, it will be four years old. Technology moves on, old blog posts do not.

So: thanks to BioStar user zx8754 for pointing me to this Stack Overflow post, in which someone complains that the code in the post does not work as described. The *by* example is now fixed.

Side note: I often find “contact the author” is the most direct approach to solving this kind of problem 😉 always happy to be contacted.
