R help - May 2009 - What package I use to draw 3D plot after plsda?

Hi.

I was used to draw 2D plot to show distribution of my samples.  It was very
powerful in small samples.

Recently , I handle a lot of type of samples as more 15.

so, I want to use more dimention.

I was used that I conduct plsda function and draw biplot, such as,

p1=plsda(mw, sp)
biplot(p1)


How can I draw 3D graph with my data??

I don't know exactly numerical value each spot.

please, help me.

Hi,

You want something like this?

library (pls)
data(yarn)
library (scatterplot3d)

yarn.pls <- plsr(density ~ NIR, 6, data = yarn, validation = "CV")
palette (rainbow(length(yarn$density)))
scatterplot3d
(yarn.pls$scores[,1:3],pch=16,color=1:length(yarn$density),cex.symbols=2)


?scatterplot3d

B.R
