tmap extensions: tmap.networks

With tmap.networks network visualizations can be made. It will handle sfnetwork objects (from the package sfnetworks) natively.

library(sfnetworks)
library(tmap.networks)

sfn = as_sfnetwork(roxel)

Besides this new spatial data class "sfnetwork", this package also features new map layers, albeit very basic so far:

tm_shape(sfn) +
    tm_network()
#> [deprecated] The arguments `popup.vars` and `popup.format` of `tm_lines()` are
#> deprecated.
#> ℹ Use `popup` with `tm_popup()` instead, e.g. `popup = tm_popup(vars = ...,
#>   format = ...)`.
#> This message is displayed once every 8 hours.

tm_shape(sfn) +
    tm_edges(col = "type", lwd = 4) +
    tm_nodes()
