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))
```

x

Three-dimensional point pattern (object of class `"pp3"`

).

…

Arguments passed to `points`

controlling the appearance of the points.

eye

Optional. Eye position. A numeric vector of length 3 giving the location from which the scene is viewed.

org

Optional. Origin (centre) of the view. A numeric vector of length 3 which will be at the centre of the view.

theta,phi

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

Type of plot: `type="p"`

for points,
`type="h"`

for points on vertical lines,
`type="n"`

for box only.

box.front,box.back

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")`

.

cex=1.5, pch=16)
plot(X, main="", box.back=list(lty=3))
# }
