R

jtools

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.

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.
