R packages for visualizing statistical models, with tools for counterfactual simulation
Branch: master

Source code for the R packages tile and simcf:

  • tile A complete graphical system, build on grid, with strengths in tiled displays of multiple plots and in visualizing the relationships estimated by regression models, and uncertainty in those estimated relationships.

  • simcf A complementary package with a convenient scenario-builder for constructing counterfactuals for models defined by R formulas, and a collection of simple tools for simulating quantities of interest, including conditional expected values, conditional differences, relative risks, and predicted values, for a variety of regression models.

Individuals interested in contributing to either or both packages should contact Chris Adolph (
