In dr: Methods for Dimension Reduction for Regression

Description

Plots selected direction vectors determined by a dimension reduction regression fit. By default, the pairs function is used for plotting, but the user can use any other graphics command that is appropriate.

Usage

## S3 method for class 'dr'
plot(x, which = 1:x$numdir, mark.by.y = FALSE, plot.method = pairs, ...)

Arguments

x	The name of an object of class dr, a dimension reduction regression object
which	selects the directions to be plotted
mark.by.y	if TRUE, color points according to the value of the response, otherwise, do not color points but include the response as a variable in the plot.
