Solt, Frederick, Yue Hu, and Brenton Kenkel. 2026. interplot: Plot the Effects of Variables in Interaction Terms. R package version 1.2.0. The Comprehensive R Archive Network (CRAN).

interplot is a tool for plotting the conditional coefficients (“marginal effects”) of variables included in multiplicative interaction terms. The function plots the changes in the coefficient of one variable in a two-way interaction term conditional on the value of the other included variable. The resulting plot also includes simulated 95% confidence intervals of these coefficients.

To install:
