Hi All,

I have data for two groups, group with 100 points and group B with 15 points. i needed plot these two groups in one scatter plot, each group with a different color. I tried

plot3d(data, col = c("red", "blue")[c(rep(1, 100), rep(2, 15))], pch=20) . this works but the graph does not look good.

the other option that I tried is

scatterplot3d(data, type="p", highlight.3d=T, pch=16) where the graph looks much nicer but i do not know how to have each group with a different color.

Does anyone know how to do it?
Thanks
