Pairs Plot in Rfwdmv

Description

This function produces a pairs plot with sumperimposed contours.

Usage

fwdmvPrePlot(X, panel = panel.be, plot.diagonal = TRUE)

Arguments

X a matrix or data frame.
panel a function for computing the contours. The Rfwdmv package includes panel.be for bivariate ellipses, panel.me for median centered bivariate ellipses, and panel.bb for bivariate box plots.
plot.diagonal a logical value. If TRUE then univariate boxplots are drawn along the diagonal.

Value

an empty list is invisibly returned.

Note

The bivariate boxplots calculated from B-splines provide a useful tool for a preliminary examination of the data. The non elliptical shape of the countours is an indication or non normality.
