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.
