## Point and Click Interface for Exploratory Analysis of Point Pattern

### Description

Compute various summary functions for a point pattern using a point-and-click interface.

### Usage

     istat(x, xname)

### Arguments

`x` | The spatial point pattern to be analysed. An object of class `"ppp"`.
`xname` | Optional. Character string to use as the title of the dataset.

### Details

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.

### Value

`NULL`.

### Note

Before adjusting the bandwidth parameter `bw`, it is advisable to select No simulation envelopes to save a lot of computation time.

### Package Dependence

This function requires the package rpanel to be loaded.
