Returns the raw variables from the original data
frame using the get_all_vars()
but with the twist that it also performs any associated
subsetting based on the model's subset()
argument.
prGetModelData(x, terms_only = FALSE, term.label)
data.frame
The fitted model.
Only use the right side of the equation by selecting the terms
Sometimes need to retrieve specific spline labels that are not among the `labels(terms(x))`
