sidelengths.owin: Side Lengths of Enclosing Rectangle of a Window

Description

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

Usage

"sidelengths"(x)
 "shortside"(x)

Arguments

x

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

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.

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.

Examples

  w <- owin(c(0,2),c(-1,3))
  sidelengths(w)
  shortside(as.rectangle(letterR))
