Extract the window frame of a window or other spatial dataset

`as.rectangle(w, …)`

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.

A window (object of class `"owin"`

)
of type `"rectangle"`

representing a rectangle.

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.

# 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) # }
