Description: This package contains various routines for drawing
	ellipses and ellipse-like confidence regions.  There are three groups
	of routines:
	plotcorr - This routine implements the plots described in
	Murdoch, D.J. and Chow, E.D. (1996).  A graphical display of large
	correlation matrices. {\em The American Statistician} {\bf 50},178-180.
	These display correlations using ellipses, whose shape is that
	of the contours of a bivariate normal distribution with matching
	correlation.
	
	pairs.profile - This routine implements a version of the profile plots
	described in Bates and Watts (1988), Nonlinear Regression Analysis and its
	Applications.

	ellipse* - These routines provide the basis for the others, drawing
	ellipses based on various S objects, including scalar correlations,
	covariance matrices, arima.mle, lm, and nls fits.

	The following functions are still unimplemented in R:

	-postscript device for the plotcorr objects, together
	with ellipse.chars and ellipse.fonts
	-ellipse.arima.
	-profile.ms.fixed
