R help - Mar 2010 - Linear Discriminant Analysis

Hi,

I was wondering if you can show me how to plot the discriminant boundary lines
for an LD analysis in R.  I am curious as to perform this on a larger scale, so
I was wondering if you can provide me an example on the infamous 'iris'
data.

Here's what I have so far:
iris.lda=lda(Species ~., data=iris)
iris.lda
plot(iris.lda)

col <- rep(c("red", "black", "blue"), each=50)
pch <- rep(1:3, each=50)
plot(iris.lda, col=col, pch=pch)


% This will not  work to plot the coefficients.

abline(lda(Species~.,data=iris)$scaling, col="black")  

Thanks,

Lee
