Configure inset map settings

Create and store an inset configuration used by with_inset(). The configuration contains subplot specifications, aspect ratio of the main plot, CRS settings, and border appearance for insets.

Usage

config_insetmap(
  data_list,
  specs,
  crs = sf::st_crs("EPSG:4326"),
  border_args = list()
)

Arguments

data_list

A list of spatial data objects (sf class). These data are used to compute the overall bounding box and coordinate systems for the insets.

specs

A non-empty list of inset_spec() objects.

crs

Coordinate reference system to transform to, passed to ggplot2::coord_sf() as crs. Default "EPSG:4326".

border_args

A list of named arguments passed to map_border() to style the borders around inset plots. See map_border() for details (defaults: color = "black", linewidth = 1).

Value

An object of class insetcfg. Also stored as the last configuration, retrievable via last_insetcfg().
