Why is the function to print out text in R named "cat"? Why is the function to delete objects called "rm"?

Jeromy Anglim explains the provenance of many of R’s command names in this post: the details are not only interesting in their own right, but the etymology may also serve as a memory guide next time you’re searching for the function to find matching text in character vectors ("grep").
