Plot Ellipses
This function plots ellipses according to a covariance matrix
do.ellipses(acov, pos, ...)
acov |
the given covariance matrix |
pos |
the location of the ellipse |
... |
further graphical parameter for the ellipses |
The correlation matrix of the given covariance is computed and the resulting ellipse is plotted. The radi is computed with the singular value decomposition and the cos/sin is calculated for 100 different degrees.
