Thanks to Dirk for pointing it out in my blog : "thomas" and "tlumley"
are the same person. Also "martyn" and "plummer", and "paul" and
"murrell" ... updated number of commits per author below

Not quite sure who "r" is (96 commits) and "mike" (1 commit). Also there
are 203 commits that have "(no author)"
The other thing is that it does not include data from the pre-svn era.

Hello,
Today, Brian Ripley commited the revision 50000 of R's svn repository.
I took this as an opportunity to do some data analysis of the log and
posted some code and graphics on my blog:

The plots of the number of commits per day (and per month) indicates a
peak in 2002.
Here are the top 20 modified files :
