View source: R/geom_ellipse_cm.R
This layer uses centimeter as unit to draw ellipse so that its size and shape will not be influenced by the coordinate systems (even when a polar system is used).

Accepted properties are:
(1) rcm
radius in centimeter.
(2) ab
it means to what extent
radius a of an ellipse is larger than radius b.
However, its true meaning is the aspect ratio which
is used by gridExtra::ellipseGrob
and indicates
the extent to which y dimension is flattened. So, say,
when ab = 2
, radius a is larger than b, but it is
not exactly 2 times larger.
(3) color
color of the the outline.
(4) fill
color inside the shape.
(5) alpha
alpha of color and fill.
(6) size
line width of the outline.
(7) linetype
line type.
(8) angle
angle of rotation from 0
degree and in anti-clockwise direction.
(9) n
the number of points to
draw the shape. Note: it must be written inside
the aes(...)
function.
(10) x
x coordinates of middle points.
(11) y
y coordinates of middle points.
