Converts a window to another unit of length.

```
# S3 method for owin
rescale(X, s, unitname)
```

X

Window (object of class `"owin"`

).

s

Conversion factor: the new units are `s`

times the old units.

unitname

Optional. New name for the unit of length.
See `unitname`

.

Another window object (of class `"owin"`

) representing the same
window, but expressed in the new units.

This is a method for the generic function `rescale`

.

The spatial coordinates in the window `X`

(and its window) will be re-expressed
in terms of a new unit of length that is `s`

times the current
unit of length given in `X`

.
(Thus, the coordinate values are *divided* by `s`

,
while the unit value is multiplied by `s`

).

The result is a window representing the *same* region of space,
but re-expressed in a different unit.

If `s`

is missing, then the coordinates will be re-expressed
in ‘native’ units; for example if the current unit is
equal to 0.1 metres, then the coordinates will be re-expressed in metres.

# NOT RUN { data(swedishpines) W <- Window(swedishpines) W # coordinates are in decimetres (0.1 metre) # convert to metres: rescale(W, 10) # or equivalently rescale(W) # }
