question about cleaning up data labels on a plot3d plot

text3d(x, y, z, text=letters[1:10], cex=2

Thank you for the help. Is there a way to remove the text from the plot as well.

I am finding it difficult to see what I am looking for with the text in the way. It 
would be useful to be able to identify a point and then clear the text. Can that be 
done while still maintaining the orientation of the plot?
