dr.coplot

object

specify the indices of the directions to be plotted

which

if FALSE, plot the response versus the first specified
  direction conditioning on the second specified direction.  If TRUE, plot
  first direction versus second direction conditioning on the third
  direction, using the response as a marking variable to 

mark.by.y

This function produces a coplot of the response versus specified
  directions in dimension reduction regression.

regression

Functions, methods, and datasets for fitting dimension
 reduction regression, including pHd and inverse regression methods
 SIR and SAVE.  These methods are described, for example, in
 R. D. Cook (1998), Regression Graphics, Wiley, New York.  Also included is
 code for computing permutation tests of dimension.  Adding additional
 methods of estimating dimension is straightforward.  One function depends
 on the lqs package.  Minor revision to be compatible with R 1.6, and one
 bug-fix.
