Support empty selections in all recipe steps
EmilHvitfeldt opened this issue · comments
@DavisVaughan do I still need to apply this change since these steps require a single selection to work? Or does an empty selection mean that no action is being taken?
Probably still worth updating if it isn't too hard. I changed the "single variable" steps in recipes to be "at most one variable" https://github.com/tidymodels/recipes/blob/558625689b0b4c87761cd934acc3972ff5e581e6/R/regex.R#L108
