print_contrasts

Utility to print all contrast matrices for a given dataframe.
Displays fractional values with <code><a href="/link/MASS%3A%3Afractions()?package=contrastable&version=1.1.0" data-mini-rdoc="contrastable::MASS::fractions()">MASS::fractions()</a></code>.
Prints nothing if there are no factor columns in the dataframe.

Quickly set and summarize contrasts for factors prior to regression analyses. Intended comparisons, baseline conditions, and intercepts can be explicitly set and documented without the user needing to directly manipulate matrices. Reviews and introductions for contrast coding are available in Brehm and Alday (2022)<doi:10.1016/j.jml.2022.104334> and Schad et al. (2020)<doi:10.1016/j.jml.2019.104038>.
