If you take this great new paper and print out any figure you could approach any scientist on earth from a long distance holding it up. As soon as they could see it at all, they'd know - everything in this paper is written in R. Which is totally cool, I'm not making fun. It's just the most R'y proteomics paper I've opened in a while.
What is it? It's a statistically valid way of taking your PTM level peptide data and normalizing it against your whole protein data, so you can get stuff like relative phospho-site occupancy per molecule. Great for those biologists who expect this to be the standard output in a PTM study.
