Extensions to 'tmap' with Two New Modes: 'mapbox' and 'maplibre'

The 'tmap' package provides two plotting modes for static and interactive thematic maps. This package extends 'tmap' with two additional modes based on 'mapbox' <https://mapbox.com> and 'maplibre' <https://maplibre.org>. These modes feature interactive vector tiles, globe views, and other modern web-mapping capabilities, while using the same 'tmap' syntax for creating maps (Tennekes 2018, <doi:10.32614/RJ-2018-027>).
