Feature request: scoped shadow_recode variants #274

Open antondutoit opened 4 years ago

antondutoit commented 4 years ago

Pretty self-explanatory I guess .. ?

These would be terrific when there are large numbers of variables which by their nature will have a particular type of missingness, e.g. a questionnaire with filter questions that lead to other questions being skipped (or, in pseudocode, where Q1 is the filter, IF Q1 = "no", GOTO Q5; ELSE GOTO Q2).

This is related to #249 - a superset of it I suppose.

I also note #262 below about the use of across() instead of scoped variants, which may impinge on this request. But whichever implementation is used, it'd be nice to have a parsimonious way to do this which is baked in. The familiar ~_all, ~at and ~if makes things easier too.

Yup, this is a great feature request, and something that I've wanted to implement, but it's great to have someone who will be there to help kick the wheels, so thank you for posting!

It'll be a few weeks as I'm taking a holiday but will return to this.

Thanks for posting the issue
