FlowingData reader Chris asks:
I was wondering, have you ever considered doing a Chernoff faces tutorial for R? I think Chernoff faces are pretty interesting and I haven't seen much about them on the web.
This wasn't the first time someone's asked how to make Chernoff faces, so I did a quick search. Guess what. There's an R package for that. This tutorial describes how to apply Chernoff faces to your own data.
