Hello
I've created a 3d scatterplot, and had no problems labeling the points.
However, I've been really struggling to change the color of the points based
on a factor (see 'group' below). Is such a thing possible?
My data look like this:
food group x y z
apple fruit 0.216 -0.112 -0.893
orange fruit 0.814 0.097 0.460
broccoli veg -0.239 0.240 -0.425
banana fruit 0.222 0.968 -0.050
parsnip veg 0.139 0.897 0.378
garlic veg -0.104 0.510 -0.400
pca <- read.table(...
p3d<- plot3d(pca$x, pca$y, pca$z, xlab="Component 1", ylab="Component 2",
zlab="Component 3", col="blue",box=FALSE, size=5)
food.v<-as.vector(pca$food)
text3d(pca$x, pca$y, pca$z, food.v, cex=0.9, adj = 1)
Many thanks,
Leigh
