R: Side Lengths of Enclosing Rectangle of a Window

sidelengths.owin {spatstat.geom} | R Documentation

## Side Lengths of Enclosing Rectangle of a Window

### Description

Computes the side lengths of the (enclosing rectangle of) a window.

### Usage

     ## S3 method for class 'owin'
    sidelengths(x)

     ## S3 method for class 'owin'
    shortside(x)

### Arguments

`x` | A window whose side lengths will be computed. Object of class `"owin"`.

### Details

The functions `shortside` and `sidelengths` are generic. The functions documented here are the methods for the class `"owin"`.

`sidelengths.owin` computes the side-lengths of the enclosing rectangle of the window `x`.

For safety, both functions give a warning if the window is not a rectangle. To suppress the warning, first convert the window to a rectangle using `as.rectangle`.

`shortside.owin` computes the minimum of the two side-lengths.

### Value

For `sidelengths.owin`, a numeric vector of length 2 giving the side-lengths (x then y) of the enclosing rectangle. For `shortside.owin`, a numeric value.

      sidelengths(w)
      shortside(as.rectangle(letterR))
