Error in plot.xy(xy.coords(x, y), type = type, ...) :

Does anyone know what he problem is?
Hi Nancy, When you "rep" your colors, the second argument should be a number equal to the number of values.
The syntax rep(x, c(100,15)) is legal: it says to repeat the first value 100 times, the second 15 times. I try the line above and it works with no error. SNN is not telling us something, but I don't know what. Perhaps the content of data is relevant, or the content of his/her workspace, or whatever. Duncan Murdoch That is, if "data" contains 100 x, y and z
components, try:
scatterplot3d(data,color=rep(c("red","blue"),50),pch=16)
My guess is that you are generating NAs or something with your version.
Jim
