h.plot: Detection hazard plotting.

In DistanceDevelopment/hsltm: Line transect estimation with hidden state availability models

Description

Plots detection hazard contours.

Usage

h.plot(hfun, pars, dat = NULL, models = NULL, xrange = c(0, 50),
  yrange = xrange, nx = 50, ny = nx, type = "contour",
  nlevels = 20, add = FALSE, col = "black", logscale = FALSE,
  xlab = "Perpendicular distance", ylab = "Forward distance",
  theta = 90, phi = 35, ...)

Arguments

hfun	detection hazard function name
pars	detection hazard function parameter vector
dat	data frame.
models	model list, as for est.hmltm for example.
xrange	range of x-axis.
yrange	range of y-axis.
nx	number of points on x-axis at which to evaluate detection hazard function.
ny	number of points on y-axis at which to evaluate detection hazard function.
type	"contour", "persp", "image" or "both" (for image and contour).
nlevels	number of contour levels.
add	if TRUE adds to existing plot, else creates new plot.
col	colour of plot.
logscale	If TRUE, plots hazard values on log scale.
xlab	x label.
ylab	y label.
theta	argument for image.
phi	argument for image.
...	other arguments to image, contour or persp.
