Off topic:Add Labels To Groups In Plot3D

Question

[Assa Yeroslaviz]

Hi,

I am doing a 3d pca in R and would like to add the names of the groups to the image.

popn <- round(pca$x[,1])
colour <- popn - min(popn) + 1
pc <- princomp(NormalisedResult)
plot3d(pca$x[,1:3], col=colour, size=5.0)

this is how I create the plot.

When I am using the text3d command to add some text it fails.

text3d=(texts=fileName,col="blue")
Error: unexpected ',' in "text3d=(texts=fileName,"

doing it w.o. the col option give no error, but I can't see any text on the image.

Is there a way of adding the column names to the plot?

Thanks Assa
