plot.movecost_accum: Plot an accumulated cost surface

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 an accumulated cost surface

Description

Returns a ggplot object showing the accumulated cost surface with isolines and origin location(s), or the isolines alone (type = "contour"), reproducing the two output types of movecost <= 2.x's outp parameter - but on demand, without re-running the analysis.

Usage

## S3 method for class 'movecost_accum'
plot(
  x,
  type = c("raster", "contour"),
  cont.lab = TRUE,
  transp = 0.5,
  cex.breaks = 2.5,
  iso.col = "white",
  iso.lwd = 0.3,
  ...
)

Arguments

x	a movecost_accum object.
type	"raster" (default; accumulated surface, slope-shade, isolines) or "contour" (isolines only).
cont.lab	TRUE (default) or FALSE: label the isolines.
transp	transparency of the slope-shade overlay (0.5 by default).
cex.breaks	size of the isoline labels (2.5 by default, in ggplot2 text-size units).
iso.col	colour of the isolines and their labels (default "white", which reads clearly against the dark low-cost core of the viridis "C" palette; over the "contour" output, where there is no coloured background, "grey20" is used automatically unless the user overrides iso.col).
iso.lwd	line width of the isolines (0.3 by default).
...	unused.

Value

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