Numeric vector denoting the coordinates of the center or position of the rectangle.

size

Numeric vector denoting the width and height of the rectangle.

orientation

Numeric denoting the orientation of the rectangle in radians. Defauls to 0.

                          center = c(0, 0), 
                          size = c(2, 2))
