Plots a three-dimensional point pattern.
# S3 method for pp3
plot(x, ..., eye=NULL, org=NULL, theta=25, phi=15,
type=c("p", "n", "h"),
box.back=list(col="pink"),
box.front=list(col="blue", lwd=2))
Three-dimensional point pattern (object of class "pp3"
).
Arguments passed to points
controlling the appearance of the points.
Optional. Eye position. A numeric vector of length 3 giving the location from which the scene is viewed.
Optional. Origin (centre) of the view. A numeric vector of length 3 which will be at the centre of the view.
Optional angular coordinates (in degrees) specifying the direction
from which the scene is viewed: theta
is the azimuth
and phi
is the colatitude. Ignored if eye
is given.
Type of plot: type="p"
for points,
type="h"
for points on vertical lines,
type="n"
for box only.
How to plot the three-dimensional box that contains the points.
A list of graphical arguments passed to segments
,
or a logical value indicating whether or not to plot
the relevant part of the box. See Details.
Null.
This is the plot method for objects of class "pp3"
.
It generates a two-dimensional plot of the point pattern x
and its containing box as if they had been viewed from the
location specified by eye
(or from the direction
specified by theta
and phi
).
The edges of the box at the ‘back’ of the scene (as viewed from the
eye position) are plotted first. Then the points are added. Finally the
remaining ‘front’ edges are plotted. The arguments
box.back
and box.front
specify graphical parameters for
drawing the back and front edges, respectively. Alternatively
box.back=FALSE
specifies that the back edges shall not be drawn.
Note that default values of arguments to plot.pp3
can be set by spatstat.options("par.pp3")
.
