stat_geohash: Display rectangles representing each geohash

In mitre/aviationgeoms: easy bake aviation ggplot

Description

Display rectangles representing each geohash

Usage

stat_geohash(
  mapping = NULL,
  data = NULL,
  geom = "rect",
  position = "identity",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

Arguments

mapping	Set of aesthetic mappings created by aes or aes_. If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.
data	The data to be displayed in this layer. There are three options: If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot. A data.frame, or other object, will override the plot data. All objects will be fortified to produce a data frame. See fortify for which variables will be created. A function will be called with a single argument, the plot data. The return value must be a data.frame., and will be used as the layer data.
geom	The geometric object to use display the data
position	Position adjustment, either as a string, or the result of a call to a position adjustment function.
na.rm	logical. Should this layer remove NA values
inherit.aes	If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. borders.
...	Additional parameters to the geom and stat.
show.legnd	logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes.

Details

Given a data.frame containing a list of geohash character strings, plot rectangles corresponding to the error boxes for each geohash.

stat_geohash understands the following aesthetics (required aesthetics are in bold)

• geohash

• alpha

• colour

• fill

• linetype

• size

Examples

df <- data.frame(geohash=c("SSW","S1W"), stringsAsFactors = FALSE)
library(ggplot2)
ggplot(df, aes(geohash=geohash))+stat_geohash()
ggplot(df, aes(geohash=geohash))+geom_rect(stat="geohash") +coord_quickmap()
