Icicle layout for a Geoscale

Rectangle coordinates for a level-by-level structure plot: one row per level, each region a rectangle whose width is its share of the weight. Exposed so the layout can be drawn with something other than ggplot2.

Usage

geo_layout(x, weight = NULL)

Arguments

x

A Geoscale.

weight

Weight column. NULL uses the default.

Value

A data.frame with columns level, region, rank, xmin, xmax, ymin, ymax, weight, share.

head(geo_layout(geoscale_example()))
