This function produces a coplot of the response versus specified directions in dimension reduction regression.
dr.coplot(object, which=1:object$numdir, mark.by.y=F, ...)
object |
a dr object |
which |
specify the indices of the directions to be plotted |
mark.by.y |
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 color the points. |
