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.
