# as.rectangle

##### Window Frame

Extract the window frame of a window or other spatial dataset

##### Usage

`as.rectangle(w, …)`

##### Arguments

- w
A window, or a dataset that has a window. Either a window (object of class

`"owin"`

), a pixel image (object of class`"im"`

) or other data determining such a window.- …
Optional. Auxiliary data to help determine the window. If

`w`

does not belong to a recognised class, the arguments`w`

and`…`

are passed to`as.owin`

to determine the window.

##### Details

This function is the quickest way to determine a bounding rectangle for a spatial dataset.

If `w`

is a window, the function
just extracts the outer bounding rectangle
of `w`

as given by its elements `xrange,yrange`

.

The function can also be applied to any spatial dataset that has a window:
for example, a point pattern (object of class `"ppp"`

) or
a line segment pattern (object of class `"psp"`

).
The bounding rectangle of the window of the dataset is extracted.

Use the function `boundingbox`

to compute the *smallest*
bounding rectangle of a dataset.

##### Value

A window (object of class `"owin"`

)
of type `"rectangle"`

representing a rectangle.

##### Examples

```
# NOT RUN {
w <- owin(c(0,10),c(0,10), poly=list(x=c(1,2,3,2,1), y=c(2,3,4,6,7)))
r <- as.rectangle(w)
# returns a 10 x 10 rectangle
data(lansing)
as.rectangle(lansing)
data(copper)
as.rectangle(copper$SouthLines)
# }
```
