rescale
From spatstat v1.11-8
by Adrian Baddeley
Convert dataset to another unit of length
Converts between different units of length in a spatial dataset, such as a point pattern or a window.
Usage
rescale(X, s)
Arguments
- X
- Any suitable dataset representing a two-dimensional
object, such as a point pattern (object of class
"ppp"
), or a window (object of class"owin"
). - s
- Conversion factor: the new units are
s
times the old units.
Details
This is generic. Methods are provided for
point patterns (rescale.ppp
)
and windows (rescale.owin
).
The spatial coordinates in the dataset X
will be re-expressed
in terms of a new unit of length that is s
times the current
unit of length given in X
.
Value
- Another object of the same type, representing the same data, but expressed in the new units.
Note
The result of this operation is equivalent to the original dataset.
If you want to actually change the coordinates by
a linear transformation, producing a dataset that is not equivalent
to the original one, use affine
.
