plot.movecost_alloc: Plot cost-allocation zones

In movecost: Calculation of Slope-Dependant Accumulated Cost Surface, Least-Cost Paths, Least-Cost Corridors, Least-Cost Networks Related to Human Movement Across the Landscape

Plot cost-allocation zones

Description

Returns a ggplot object showing the cost-allocation zones (one colour per origin), with the origins and, optionally, the isolines of the minimum accumulated cost surface.

Usage

## S3 method for class 'movecost_alloc'
plot(
  x,
  isolines = FALSE,
  transp = 0.5,
  iso.col = "white",
  iso.lwd = 0.3,
  origin.lab = TRUE,
  cex.origin.lab = 3,
  ...
)

Arguments

x	a movecost_alloc object.
isolines	TRUE or FALSE (default): overlay the cost isolines.
transp	transparency of the slope-shade overlay (0.5 by default).
iso.col	colour of the isolines (default "white", which reads clearly against the coloured allocation zones).
iso.lwd	line width of the isolines (0.3 by default).
origin.lab	TRUE (default) or FALSE: label each origin with its index. The indices match the zone identifiers (the cell values of the allocation raster and the origin_id of zones), so each origin can be related to the zone allocated to it.
cex.origin.lab	size of the origin labels (3 by default, in ggplot2 text-size units).
...	unused.

Value

A ggplot object (draw it by printing; customise it with +).
