zb_plot {zonebuilder}

Plot zones

Description

This function opens a static map of the zones

Usage

zb_plot(
  z,
  palette = c("rings", "hcl", "dartboard"),
  title = NULL,
  text_size = c(0.3, 1),
  zone_label_thres = 0.002
)

Arguments

z

An 'sf' object containing zones covering the region

palette

Palette type, one of "hcl" (a palette based on the HCL color space), "rings" (a palette which colors the rings using the YlOrBr color brewer palette), "dartboard" (a palette which resembles a dartboard)

title

Plot title

text_size

Vector of two numeric values that determine the relative text sizes. The first determines the smallest text size and the second one the largest text size. The largest text size is used for the outermost circle, and the smallest for the central circle in case there are 9 or more circles. If there are less circles, the relative text size is larger (see source code for exact method)

zone_label_thres

This number determines in which zones labels are printed, namely each zone for which the relative area size is larger than 'zone_label_thres'.

Value

A static plot created using R's base 'graphics' package

Examples

zb_plot(zb_zone(london_c()))
