Computes the diameter of a window.

```
# S3 method for owin
diameter(x)
```

x

A window whose diameter will be computed.

The numerical value of the diameter of the window.

This function computes the diameter of a window of arbitrary shape, i.e. the maximum distance between any two points in the window.

The argument `x`

should be a window (an object of class
`"owin"`

, see `owin.object`

for details)
or can be given in any format acceptable to `as.owin()`

.

The function `diameter`

is generic. This function is the
method for the class `"owin"`

.

# NOT RUN { w <- owin(c(0,1),c(0,1)) diameter(w) # returns sqrt(2) diameter(letterR) # }
