ggmapinset (version 0.4.0)

build_sf_inset_layers: Build layers to implement an inset-compatible geometry

Description

For plotting, use geom_sf_inset() instead. This helper is intended to be used when implementing custom geometries based on geom_sf_inset() so that they can provide parameters to control the inset.

Usage

build_sf_inset_layers(
  data,
  mapping,
  stat,
  position,
  show.legend,
  inherit.aes,
  params,
  inset,
  map_base = "normal",
  map_inset = "auto"
)

Value

A ggplot layer, or a pair of layers.

Arguments

data, mapping, stat, position, show.legend, inherit.aes, params

See ggplot2::layer().

inset

Inset configuration; see configure_inset(). If NA (the default), this is inherited from the coord (see coord_sf_inset()).

map_base

Controls the layer with the base map. Possible values are "normal" to create a layer as though the inset were not specified, "clip" to create a layer with the inset viewport cut out, and "none" to prevent the insertion of a layer for the base map.

map_inset

Controls the layer with the inset map. Possible values are "auto" to choose the behaviour based on whether inset is specified, "normal" to create a layer with the viewport cut out and transformed, and "none" to prevent the insertion of a layer for the viewport map.

Examples

my_custom_geom <- function(
  mapping = ggplot2::aes(),
  data = NULL,
  stat = "my_custom_stat",
  position = "identity",
  ...,
  inset = NA,
  map_base = "normal",
  map_inset = "auto",
  na.rm = TRUE,
  inherit.aes = TRUE
) {
  params <- rlang::list2(na.rm = na.rm, ...)
  build_sf_inset_layers(
    data = data, mapping = mapping,
    stat = stat, position = position,
    show.legend = show.legend,
    inherit.aes = inherit.aes,
    params = params,
    inset = inset,
    map_base = map_base,
    map_inset = map_inset
  )
}
