Strip unplottable admin levels out of a pre-plot data structure

Walks the pre-plot list and drops any element whose `admin_level` name is listed in `adm_to_drom` for that element's `pti_codes`.

Usage

drop_inval_adm(dta, adm_to_drom)

Arguments

dta

A pre-plot list as produced upstream of the plotting modules – each element has at least a `pti_codes` slot and a named `admin_level`.

adm_to_drom

Named list keyed by `pti_codes` whose values are the admin-level names to remove for that PTI – typically the output of [get_min_admin_wght()].

Value

The input list with offending elements removed.
