StatDistrictCoordinates: Label Map Regions

In alarm-redist/ggredist: Scales, Geometries, and Extensions of 'ggplot2' for Election Mapping

Label Map Regions

Description

Aggregates shapefile according to the group aesthetic and positions labels for each region defined by group. By default, labels will be sized in rough proportion to the available area.

Usage

geom_district_text(
  mapping = NULL,
  data = NULL,
  position = "identity",
  na.rm = FALSE,
  adjust = 1,
  check_overlap = FALSE,
  parse = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

geom_district_label(
  mapping = NULL,
  data = NULL,
  position = "identity",
  na.rm = FALSE,
  label.padding = ggplot2::unit(0.25, "lines"),
  label.r = ggplot2::unit(0.15, "lines"),
  label.size = 0.25,
  check_overlap = FALSE,
  parse = FALSE,
  adjust = 1,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

stat_district_coordinates(
  mapping = NULL,
  data = NULL,
  geom = "text",
  position = "identity",
  na.rm = FALSE,
  adjust = 1,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

Arguments

mapping	Set of aesthetic mappings created by aes()
data	The data to be displayed in this layer
position	Position adjustment
na.rm	if TRUE, will silently remove missing values from calculations
adjust	A multiplicative scaling factor for the default label sizes
check_overlap	If TRUE, text that overlaps previous text in the same layer will not be plotted.
parse	If TRUE, the labels will be parsed into expressions and displayed as described in ?plotmath.
show.legend	Should this layer be included in the legends?
inherit.aes	If FALSE, overrides the default aesthetics, rather than combining with them.
...	Passed onto the underlying geoms.
label.padding	Padding around label
label.r	Radius of rounded corners
label.size	Size of label border (mm)
geom	The geometric object to use display the data

Value

a ggproto object

Examples
