est1 
The shape matrix of interest. A list with the components 
est2 
An optional additional shape matrix. A list with the components 
est3 
An optional additional shape matrix. A list with the components 
X 
a numeric data frame or matrix. Optional data points on which the estimates could have been based. 
alim 
can be 
color.ell 
vector of length 3 that gives the colors for the corresponding estimates 
color.points 
the color of the data points. 
lty.ell 
line types of the confidence ellipsoids. 
pch.ell 
plotting symbols for the location estimates, the centers of the confidence ellipsoids. 
lwd.ell 
line width values of the confidence ellipsoids. 
cex.ell 
cex values for the location estimates, the centers of the confidence ellipsoids. 
pch.points 
plotting symbol for the data points 
level 
The proportion of the data points that should be inside the ellipses. If there is no data the value for 
npoints 
the number of points used to approximate each ellipsoid. 
x.legend 
vertical position of the legend. By default tries to find for 2 to 4 dimensional data a good location. If 
y.legend 
horicontal position of the legend. By default tries to find for 2 to 4 dimensional data a good location. If 
cex.legend 

pty 

gap 
distance between subplots, in margin lines. 
oma.bottom 

labels 
optional labels for the diagonals. 
cex.labels 

main 
optional title of the plot. 
... 
further arguments passed to or from other methods. 
All scatter matrices are standardized to have determinant 1. If X
is given, the Mahalanobis distances based on the location and shape estimates are computed, and t
in the function ellipse
is the level quantile of the Mahalanobis distances. If no X
is provided t
equals level
.
The location of the legend is currently problematic and it is recommended that the user should provide the coordinates for the legend.
A scatter plot matrix.
