.msg_if_ordered_reset

Ordered factors use orthogonal polynomials (contr.poly) by default with
k number of levels -1 (k-1) of trend comparisons. If you use these functions
to set the contrasts to something else, the ordered class (hence ordering
to the levels) will remain but the contrasts will be set to something else.

internal

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>.
