R: Square Window

square {spatstat} | R Documentation

## Square Window

### Description

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] * [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] * [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.
