Plot a concentration ellipse obtained from ConcEllipse.
## S3 method for class 'ellipse' plot(x, add = TRUE, labeled = FALSE, center = FALSE, centerlabel = "Center", initial = FALSE, ...)
x |
An object with class |
add |
Should the ellipse be added to the current plot? |
labeled |
Should the ellipse be labelled with the confidence level? |
center |
Should the center be plotted? |
centerlabel |
Label for the center. |
initial |
Should the initial data be plotted? |
... |
Any other graphical parameter that can affects the plot (as color, etc ...). |
