h_construct_model_frame_inputs {mmrm} | R Documentation |
Construction of Model Frame Formula and Data Inputs
Description
Input formulas are converted from mmrm-style to a style compatible
with default stats::model.frame()
and stats::model.matrix()
methods.
The full formula is returned so we can construct, for example, the
model.frame()
including all columns as well as the requested subset.
The full set is used to identify rows to include in the reduced model frame.
