leaflet 2.2.1
- When
addProviderTiles()
is used with{leaflet.providers}
version 2.0.0 or later, theleaflet-providers
HTML dependency produced can be correctly cached by knitr. When used with older versions of{leaflet.providers}
, the HTML dependency uses temp files that break knitr's caching mechanism (thanks @qdread, @jaredlander; #884).
