Contributions to the R source

One of the nice things about tracking the R subversion repository using git instead of subversion is you can do

git shortlog -s -n

which gives you

These data are since 1997 so for Brian Ripley, that’s 3.6 commits per day for the last 15 years. 

I think that number 1 position will be out of reach for a while. 

By the way, I highly recommend to anyone tracking subversion repositories that they use git to do it. You get all of the advantages of git and there are essentially no downsides.
