Provide utility for layering tfrmt objects together. If both tfrmt's have values, it will preferentially choose the second tfrmt by default. This is an alternative to piping together tfrmt's
layer_tfrmt(x, y, ..., join_body_plans = TRUE)
tfrmt object
When combining two body_plans, the body plans will stack together, first the body plan from x tfrmt then y tfrmt. This means that frmt_structures in y will take priority over those in x.
Combining two tfrmt with large body_plans can lead to slow table evaluation.
Consider setting join_body_plan
to FALSE
. Only the y body_plan
will be
preserved.
