In excursions: Excursion Sets and Contour Credibility Regions for Random Fields

Define a color map for displaying contour maps.

Description

contourmap.colors calculates suitable colours for displaying contour maps.

Usage

contourmap.colors(lp, zlim, col, credible.col)

Arguments

lp	A contourmap calculated by contourmap, contourmap.inla, or contourmap.mc
zlim	The range that should be used (optional). The default is the range of the mean value function used when creating the contourmap.
col	The colormap that the colours should be taken from.
credible.col	The color that should be used for displaying the credible regions for the contour curves (optional).

Examples

n <- 10
Q <- Matrix(toeplitz(c(1, -0.5, rep(0, n - 2))))
map <- contourmap(
  mu = seq(-5, 5, length = n), Q, n.levels = 2,
  compute = list(F = FALSE), max.threads = 1
)
cols <- contourmap.colors(map,
  col = heat.colors(100, 1),
  credible.col = grey(0.5, 1)
)
