Plot post_array or post_table with ggplot2

Plots the changing or summary geometries in a post_array or post_table as facets defined by the first non spatial dimension. Other dimensions are discarded.

Usage

autoplot.post_array(
  object,
  attribute = NULL,
  max_plot = 9,
  geom_sum = FALSE,
  ...
)

autoplot.post_table(
  object,
  attribute = NULL,
  max_plot = 9,
  geom_sum = FALSE,
  ...
)

Arguments

object: a post_array or post_table object
attribute: the attribute to fill the geometries
max_plot: maximum number of subplots rendered
geom_sum: should the geom_sum geometries be used for plotting? Defaults to FALSE
...: ignored

Value

an object of class ggplot

Details

See ggplot2::autoplot().

Examples

library(ggplot2)
library(sf)
arr = as_post_array(polygons, geometry_summary = summarise_geometry_union)
arr$area = st_area(arr$geometry)
autoplot(arr, area)

autoplot(arr, area, geom_sum = TRUE)

autoplot(arr, area, max_plot = 3)


tab = as_post_table(polygons, geometry_summary = summarise_geometry_union)
#> Warning: st_centroid assumes attributes are constant over geometries
autoplot(tab, gid)

autoplot(tab, gid, geom_sum = TRUE)
