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.
