geom_district_text: 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,
  ...
)

Value

a ggproto object

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
