Resources, software and data

Resources

• McMaster R users’ list info/subscription page (“A list for general help and discussion among R users at McMaster”) – intended as a friendly/low-stress channel for people to ask R questions of the campus community
• Bio data lunch mailing list (weekly lunchtime group discussions of specific data analysis problems)
• Notes on running R on HPC, especially Compute Canada

Software

I write a lot of software in R. Here are some R packages.

• “Other authors” only includes authors who contributed comparable (or larger!) amounts to the package than I did. Check out the DESCRIPTION files or help(package="whatever") for the full lists of authors and contributors.
• Package ranks and download counts computed as of 10 Jun 2026. (These metrics differ in order because packages have been on CRAN for different lengths of time.)

Data and miscellaneous

• code for spatial moment equations
• measles data
• workshop notes and materials from workshops before the Ecology and Evolution of Infectious Disease (2005, 2008-2012)
