R celebrated a milestone today, as Brian Ripley committed the 50,000th change to the R code repository. Romain François has the details, along with a fascinating look at the rate of change in graphical form using data extracted from the repository and analyzed with R. Here's the number of daily commits to R's source code over the past X years, with a smoothing line showing the trend:
Romain shows many other charts, such as commits by author over time. Romain provides the R script to download the data from svn and create the charts, so these are useful tools for anyone who wants to analyze the performance of any large-scale software project with multiple committers.
Romain François: Celebrating R commit #50000
Thanks for the echo.
Following a suggestion by Duncan Murdoch, I've updated the code to take into account days with 0 commits when calculating the smooth lines.
With this addition, the number of commits per day seems to want to go up again
