tmap.deckgl

A new mode! tmap contains two modes: "plot" (static plots) and "view" (interactive leaflet maps). With this package a new mode called "deck" is introduced. It uses the JS library DeckGL via the R package deckgl.

Proof of concept

The package serves as a proof of concept of the extendibility of tmap 4.

So far, only tm_polygons and tm_lines are working. Since the underlying package deckgl has not been updated in the last 2 years (https://github.com/crazycapivara/deckgl), further development package has low priority at the moment.

Installation

# install.packages("remotes")
install_github("r-tmap/tmap")
install_github("r-tmap/tmap.deckgl")

Example

library(tmap)
library(tmap.deckgl)

tmap_mode("deck")
tm_shape(World) +
  tm_polygons("HPI", fill.scale = tm_scale_intervals(values = "brewer.rd_yl_gn")) 
	

tm_shape(NLD_dist) +
	tm_polygons("employment_rate", 
				fill.scale = tm_scale_intervals(values = "scico.roma"),
				lwd = 0.1) +
tm_shape(NLD_muni) +
	tm_polygons(fill = NULL, lwd = 1) +
	tm_deck(pitch = 75)
