Ellipse in PCA with parameters "a" and "b"defined.
Hi,
I have to construct an ellipse interval region on a PCAbiplot, I have my
parameters "a" and "b" and I would apply the formula:
draw.ellipse(x, y, a = , b = )

and second component, but my answer is what I have to choose as X and Y into
the formula?
if "a" and "b" are scalars or
