Title: library ellipse for drawing ellipses and ellipse-like confidence regions
Author:  Duncan Murdoch <murdoch@stats.uwo.ca> and E. D. Chow
(porting to R by Jesus M. Frias Celayeta <iosu@bureau.ucc.ie>)
Maintainer: Duncan Murdoch <murdoch@stats.uwo.ca>
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
