Optional. Character string to use as the title of the dataset. |
This command launches an interactive (point-and-click) interface
which offers a choice of spatial summary functions
that can be applied to the point pattern x.
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.
NULL.
Before adjusting the bandwidth parameter bw,
it is advisable to select No simulation envelopes
to save a lot of computation time.
