compositions (version 1.01-1)

coloredBiplot: A biplot providing somewhat easier access to details of the plot.

Description

This function generates a simple biplot out of various source and allows to color the objects individually. (Warning: This preliminary version is likely to be changed in next edition)

Usage

coloredBiplot(xrf,xcol="black",ycol="red",scale=1,choice=c(1,2),pc.biplot=FALSE,pch=19,ypch=2,cex=1,xarrows=FALSE,yarrows=TRUE,...)

Arguments

xrf

some representation of the the coinformation to be plotted given by a result of princomp, prcomp or svd

xcol

The color(s) to draw the points of the first set

ycol

The color(s) to draw points or arrows of second set

scale

exponential scaling ???

choice

the components to be plotted

pc.biplot

should be scaled by sqrt(nrow(X)) ???

pch

the plotchar for the first set

ypch

the plotchar for the y component

cex

the usual cex parameter for plotting

xarrows

wether or not to plot the arrows for the first dataset

yarrows

wether or not to plot the arrows for the second dataset

...

further parameters for plot

Value

• The function is called only for the sideeffect of plotting.

Details

The functions is provided for conveniance and is to be considered experimental.
