Is there any way to plot a 3-D scatter plot for two groups on one graph? Thanks, XINLI [[alternative HTML version deleted]]

As David said, use colours or something to distinguish. For example, library(rgl) data1 <- matrix(rnorm(30), ncol=3) plot3d(data1, col="red", type="s") data2 <- matrix(rnorm(30)+2, ncol=3) plot3d(data2, col="blue", type="s", add=TRUE) Duncan Murdoch
