plotFancy

This is the back-end for the functions plotSlopes and plotCurves. Don't use it directly.

A collection of functions for interpretation and presentation
of regression analysis. These functions are used
to produce the statistics lectures in
<https://pj.freefaculty.org/guides/>. Includes regression
diagnostics, regression tables, and plots of interactions and
"moderator" variables. The emphasis is on "mean-centered" and
"residual-centered" predictors. The vignette 'rockchalk' offers a
fairly comprehensive overview. The vignette 'Rstyle' has advice
about coding in R. The package title 'rockchalk' refers to our
school motto, 'Rock Chalk Jayhawk, Go K.U.'.
