Arguments for fable_xreg_matrix (see Details)

Details

Currently the fable_xreg_matrix helper supports a single argument named default_intercept. If this argument is TRUE (passed via ... above), then the intercept will be returned in the matrix if not specified (much like the behaviour of lm()). If FALSE, then the intercept will only be included if explicitly requested via 1 in the formula.
