# square

##### Square Window

Creates a square window

##### Usage

```
square(r=1, unitname=NULL)
unit.square()
```

##### Arguments

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

- unitname
Optional. Name of unit of length. Either a single character string, or a vector of two character strings giving the singular and plural forms, respectively.

##### 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 for convenience, and to improve the readability of some code.

##### Value

An object of class `"owin"`

(see `owin.object`

)
specifying a window.

##### Examples

# NOT RUN {
W <- square(10)
W <- square(c(-1,1))
# }
```
