从 R 中的 car::scatter3d() 中删除组标签

Question

I have something like this and I want to remove the group labels from the ellipsoids

car::scatter3d(x, y, z, groups = group, surface=FALSE, grid = FALSE, ellipsoid = TRUE)

Is there a way to remove the group labels because there are overlapping and cannot be distinguished?

An illustrative example is:

car::scatter3d(x = iris$Sepal.Length, y = iris$Sepal.Width, z = iris$Petal.Length, groups = iris$Species, surface=FALSE, grid=FALSE, ellipsoid = TRUE)

Answer 1

This problem has driven me crazy for years and I haven't found a solution. The best workaround I could come up with was to change the group labels to "." and "*" so that they are barely noticeable in the plot. If I could even change the size, color, or position of the group labels that might be a better solution, but I cannot figure out how to do that either, Ideally, I would really like to be able to remove the group labels that are automatically added when ellipsoid=T as well!
