`w`	weight of the component.
`mu`	mean of the component.
`sigma`	covariance matrix of the component.
`k`	resolution used for drawaing the elliptic envelope.
`alone`	if TRUE, the component is to be plotted alone in its own window.
`col`	optional background color for the component.
`alphacol`	alpha coefficient for a component with a color.
`alphanocol`	alpha coefficient for a component with no color.
`lty`	line type for the ellipsis.
