Zoom a map without losing its projection

Show part of a map by longitude and latitude limits while keeping the projection it was drawn in. The 3.0.0 documentation zoomed with coord_quickmap(xlim, ylim), which on a projected map silently replaces the projection with an unprojected one.

Usage

zoom_map(p, xlim, ylim)

Arguments

p

A map from one of the package's map verbs.

xlim, ylim

Longitude and latitude limits, in degrees, each a pair c(min, max).

Value

p with the view limited, in the same projection.

snap <- countryatlas::world_snapshot$countries
europe <- attach_geometry(snap, geometry = "polygon") |>
  world_map(gdp_per_capita)
zoom_map(europe, xlim = c(-25, 45), ylim = c(34, 72))
