plot.intensity_surface: Plots a normal mixture intensity in 3d

In sppmix: Modeling Spatial Poisson and Related Point Processes

Description

Plot the 3d intensity surface of a Poisson point process with mixture intensity of normal components.

For examples see

http://faculty.missouri.edu/~micheasa/sppmix/sppmix_all_examples.html#plot.intensity_surface

Usage

## S3 method for class 'intensity_surface'
plot(x, truncate = TRUE, L = 256, zlims = c(0,
  0), main = "Poisson intensity surface (mixture of normal components)",
  grayscale = FALSE, ...)

Arguments

x	Object of class intensity_surface or normmix.
truncate	Requests to truncate the components of the mixture intensity to have all their mass within the window of the intensity object intsurf. Default is TRUE.
L	Length of the side of the square grid. The intensity is calculated on an L * L grid. The larger this value is, the better the picture resolution.
zlims	The limits of the z axis. Defaults to [0,1.1*max(intensity)].
main	Title for the plot.
grayscale	Logical flag to request a gray scale plot.
...	Additional parameters passed to to_int_surf().
