R help - Oct 2002 - scatterplot3d

Hello!

I have a 38x3 matrix and I would like to make a 3d plot. 
However the first 27 rows are from one class and the others are 
from other class. My target is to plot the two classes with 
different colors in the same 3d plot. Is it possible? I have 
already package scatterplot3d.

Thank you

Yes, just specify a vector containing the colours (either by names or
numbers). Example:

  X <- matrix(rnorm(3*38), ncol = 3)
  scatterplot3d(X, type = "h", 
    color = rep(c("black", "red"), c(27, 11)))
