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.
