An expanding collection of functions I’ve created for use in R. They are thus far focused on presenting and interpreting the results of regression models with a focus on two-way interactions.

Group Mean Differences

This is a Shiny app to demonstrate to students how much randomly assigned groups can differ on some measure without it actually being a significant difference.

Generate correlation matrices with complex survey data in R

The survey package is one of R’s best tools for those working in the social sciences. For many, it saves you from needing to use commercial software for research that uses survey data.
