model.matrix() may be misleading for "lme" models
...other attached packages:
[1] nlme_3.1-165
loaded via a namespace (and not attached):
[1] compiler_4.4.1 tools_4.4.1 grid_4.4.1 lattice_0.22-6
--------- snip ---------
Although this apparently solves the problem for car::Anova(), the
problem is likely more general. For example, insight::get_modelmatrix()
also reports the wrong model matrix for the "lme" model m above.
My suggestion: Include a correct model.matrix.lme() method in the nlme
package. That could be my version, but I expect that R-core could come
up with something better.
Thank you,
John
