geom_polypath: Polygons with holes in ggplot2

Description

This geometry correctly plots polygons with holes in ggplot2 at the expense of doing so (slightly) more slowly than geom_polygon. This implementation fixes a bug in the ggpolypath package, which provides similar functionality.

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

# NOT RUN {
load_longlake_data()
ggplot(df_spatial(longlake_waterdf), aes(x, y, group = piece_id)) +
  geom_polypath()

# }
