Hi R experts.

I performed an Linear Discriminant Analysis (lda) and now I want to plot the
first two axes (LDA1 and LDA2). Well MASS package have the plot.lda and
pairs.lda to do that. But, they don’t let me personalize them, once they
don’t accept the type=’n’ plot. So I start looking at the lda object
properties, trying to found out my groups (n=4) axis coordinates, curiously
I couldn’t. There is only the variables axis coordinates and some analysis
results. If I can reach this information, I’ll be able to create a
customized graph using the normal plot(), points() and par().

So the question is: How could I reach these axis coordinates inside my
object (supposing they are there somewhere, once the plot.lda and pairs.lda
are able to plot them)?

 

Thanks in advance.
