geom_polypath {ggspatial}

Polygons with holes in ggplot2

Description

This geometry used to plot polygons with holes in ggplot2 at the more correctly than geom_polygon; however, in recent R and ggplot2 versions this is no longer needed.

Usage

geom_polypath(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  rule = "winding",
  ...
)

Arguments

mapping

An aesthetic mapping, created with aes. The aesthetic will mostly likely need to contain a group mapping.

data

A data.frame containing the coordinates to plot.

stat

A statistic to apply (most likely "identity")

position

A position to apply (most likely "identity")

na.rm

Should missing coordinate be removed?

show.legend

Should a legend be shown for mapped aesthetics?

inherit.aes

Should aesthetics be inherited?

rule

A fill rule to apply. One of "winding" or "evenodd".

...

Passed to the geom and/or stat.

Value

A ggplot2 layer

Examples

library(ggplot2)
load_longlake_data(which = "longlake_waterdf")
ggplot(df_spatial(longlake_waterdf), aes(x, y, group = piece_id)) +
  geom_polypath()
