Convert Window to Another Unit of Length
Converts a window to another unit of length.
## S3 method for class 'owin': rescale(X, s)
- Window (object of class
- Conversion factor: the new units are
stimes the old units.
This is a method for the generic function
The spatial coordinates in the window
(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
(Thus, the coordinate values are divided by
while the unit value is multiplied by
The result is a window representing the same region of space, but re-expressed in a different unit.
s is missing, then the coordinates will be re-expressed
- Another window object (of class
"owin") representing the same window, but expressed in the new units.
The result of this operation is equivalent to the original window.
If you want to actually change the coordinates by
a linear transformation, producing a window that is larger or smaller
than the original one, use
data(swedishpines) W <- swedishpines$window W # coordinates are in decimetres (0.1 metre) # convert to metres: rescale(W, 10) # or equivalently rescale(W)
