Arguments

x
An object of the class "listof". Essentially a list of objects.
...
Arguments passed to plot when generating each plot panel.
main
Overall heading for the plot.
arrange
Logical flag indicating whether to plot the objects side-by-side on a single page (arrange=TRUE) or plot them individually in a succession of frames (arrange=FALSE).
nrows,ncols

Details

This is the plot method for the class "listof".

An object of class "listof" (defined in the base R package) represents a list of objects, all belonging to a common class. The base R package defines a method for printing these objects, print.listof, but does not define a method for plot. So here we have provided a method for plot.

In the spatstat package, the function density.splitppp produces an object of class "listof", essentially a list of pixel images. These images can be plotted in a nice arrangement using plot.listof. See the Example.
