tmapSubmitBasemapEquivalents: Register cross-mode basemap equivalences

In tmap: Thematic Maps

Register cross-mode basemap equivalences

Description

Used by tmap mode extensions to declare which basemap providers are visually equivalent across modes. This lets a basemap be approximated when a map is reproduced in a different mode, instead of falling back to the mode default.

Usage

tmapSubmitBasemapEquivalents(equivalents, replace = FALSE)

Arguments

equivalents	a named list of concept entries. Each entry is itself a named list with mode names (e.g. plot, view, maplibre, mapbox) as names and provider name(s) as values.
replace	if TRUE, replace the whole registry; otherwise the entries are merged by concept name (existing names are overwritten), so repeated submissions are idempotent and multiple extensions compose.
