Helper converting crosswalk tables into recode xmaps (with unit weights) #49

Closed cynthiahqy closed 1 year ago

Crosswalk to Crossmap

Check for duplicate source-target pairs
Check for link types: "one-to-one" or "one-to-many"
if only "one-to-one"; append vector of 1's as weight column
if "one-to-many"; set weight to NA and warn. -- could be useful to return this table as a "template" for manual design/entry of weights.

Crossmap to Crosswalk

DANGER of losing information, but fine to do if you only have "one-to-one" links

This could be implemented as a kind of default behaviour for as_xmap_df() if weights are not provided i.e.: as_xmap_df(crosswalk, from, to, weights = NULL).

Though I still prefer:

as_recode_xmap(crosswalk, from, to, weights_name = "weights")

This is handled by #78
