### Description

This function plots ellipses according to a covariance matrix

### Usage

    do.ellipses(acov, pos, ...)

### Arguments

`acov` | the given covariance matrix
`pos` | the location of the ellipse
`...` | further graphical parameter for the ellipses

### Details

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.
