# square

From spatstat v1.31-2
by Adrian Baddeley

##### Square Window

Creates a square window

##### Usage

```
square(r=1)
unit.square()
```

##### Arguments

- r
- Numeric. The side length of the square, or a vector giving the minimum and maximum coordinate values.

##### Details

If `r`

is a number, `square(r)`

is a shortcut for creating a window object
representing the square
$[0,r] \times [0,r]$.
It is equivalent to the command
`owin(c(0,r),c(0,r))`

.

If `r`

is a vector of length 2, then
`square(r)`

creates the square with `x`

and `y`

coordinates
ranging from `r[1]`

to `r[2]`

.
`unit.square`

creates the unit square
$[0,1] \times [0,1]$.
It is equivalent to
`square(1)`

or `square()`

or `owin(c(0,1),c(0,1))`

.

These commands are included mainly to improve the readability of some code.

##### Value

- An object of class
`"owin"`

(see`owin.object`

) specifying a window.

##### Examples

```
W <- square(10)
W <- square(c(-1,1))
```
