# Frame

##### Extract or Change the Containing Rectangle of a Spatial Object

Given a spatial object (such as a point pattern or pixel image) in two dimensions, these functions extract or change the containing rectangle inside which the object is defined.

##### Usage

`Frame(X)` # S3 method for default
Frame(X)

Frame(X) <- value

# S3 method for owin
Frame(X) <- value

# S3 method for ppp
Frame(X) <- value

# S3 method for im
Frame(X) <- value

# S3 method for default
Frame(X) <- value

##### Arguments

- X
A spatial object such as a point pattern, line segment pattern or pixel image.

- value
A rectangular window (object of class

`"owin"`

of type`"rectangle"`

) to be used as the new containing rectangle for`X`

.

##### Details

The functions `Frame`

and `Frame<-`

are generic.

`Frame(X)`

extracts the rectangle inside which `X`

is
defined.

`Frame(X) <- R`

changes the rectangle inside which `X`

is defined
to the new rectangle `R`

.

##### Value

The result of `Frame`

is a rectangular window (object of class
`"owin"`

of type `"rectangle"`

).

The result of `Frame<-`

is the updated object `X`

,
of the same class as `X`

.

##### Examples

```
# NOT RUN {
Frame(cells)
X <- demopat
Frame(X)
Frame(X) <- owin(c(0, 11000), c(400, 8000))
# }
```
