Usage

 istat(x, xname)

Arguments

xname

Optional. Character string to use as the title of the dataset.

The selected summary function is computed for the point pattern x and plotted in a popup window.

The selection of functions includes Kest, Lest, pcf, Fest ,Gest and Jest. For the function pcf it is possible to control the bandwidth parameter bw.

There is also an option to show simulation envelopes of the summary function.
