Determine the redundant columns in a model matrix
Description
This function identifies the redundant columns in a model matrix, if the model matrix is not of full rank.
Usage
redundant_cols.model.matrix(model_matrix)
Arguments
model_matrix
the model matrix, typically the result of a call to model.matrix or similar functions.
Value
a (possibly empty) character vector, with the names of the redundnat columns. Note that these names will typically include the variable name and (if the variable is treated as a factor) the name of the redundant level(s).
