##### Rotate

Applies a rotation to any two-dimensional object, such as a point pattern or a window.

- Keywords
- spatial

##### Usage

`rotate(X, angle=pi/2)`

##### 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"`

). - angle
- Angle of rotation.

##### Details

This is generic. Methods are provided for
point patterns (`rotate.ppp`

)
and windows (`rotate.owin`

).

The angle of rotation is measured in radians, anticlockwise, and the centre of rotation is the origin.

##### Value

- Another object of the same type, representing the
result of rotating
`X`

through the specified angle.

##### synopsis

rotate(X, ...)

##### Examples

```
data(cells)
X <- rotate(cells, pi/3)
plot(X)
plot(rotate(cells$window, pi/4))
```
