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:
http://romainfrancois.blog.free.fr/index.php?post/2009/10/09/celebrating-R-commit-50000
The plots of the number of commits per day (and per month) indicates a
peak in 2002.
Here are the top 20 modified files :
> most.updated <- head( sort( table( data$file ), decreasing=TRUE ), 20 )
> cat( sprintf( "%40s : %6d", names(most.updated), most.updated ),
sep ="\n" )
