spikemap: Plot a Spike Map

In rCarto/spikemap: Plot Maps Made of Spikes

Description

Plot a layer of spikes on a map.

Usage

spikemap(
  x,
  var,
  inches = 3,
  width = 0.02,
  fixmax,
  col = "white",
  border = "red",
  lwd = 0.5,
  legend.pos = "bottomleft",
  legend.title.txt = var,
  legend.title.cex = 0.8,
  legend.values.cex = 0.6,
  legend.values.rnd = 0,
  add = TRUE
)

Arguments

x	an sf object, a simple feature collection.
var	name of the numeric field in x to plot.
inches	size of the tallest spike, in inches.
width	width of the spike's base.
fixmax	value of the tallest spike (see Details).
col	filling color of the spikes.
border	border color of the spikes.
lwd	width of spikes borders.
legend.pos	position of the legend, "bottomright", or a vector of two coordinates in map units (c(x, y)). If legend.pos is "n" then the legend is not plotted.
legend.title.txt	title of the legend.
legend.title.cex	size of the legend title.
legend.values.cex	size of the values in the legend.
legend.values.rnd	number of decimal places of the values displayed in the legend.
add	whether to add the layer to an existing plot (TRUE) or not (FALSE).

Details

Two maps with the same inches and fixmax parameters will be comparable.

Examples

library(sf)
com <- st_read(system.file("gpkg/com.gpkg", package="spikemap"))
plot(st_geometry(com))
spikemap(x = com, var = "pop")
