I am using two packages, 'scatterplot3d''s 'scatterplot3d' function and 'rgl''s 'plot3d' function to visualize 3 dimensional dataset.
I've done a clustering analysis, and want to markdown each center point of clusters to the graph.
First of all, maximum length of each sides of 3d plot is 100, as you can see(following is plot3d version)
The following is the data that contains the coordinates of centers of each cluster, whose name is 'kmeans_1$centers'.
mobility proximity centrality 1 80.037 76.545 17.211 2 14.767 82.608 48.853 3 29.133 48.644 70.497 4 78.005 28.132 28.382 5 50.950 17.280 85.630
Thus, I want to mark '1' at point of (mobility = 80.037, proximity = 76.545, centrality = 17.211), and same as 2/3/4/5. What I want to do is it is very unconvenient to match which cluster ID is for which color of cluster in graph.
There are tons of materials I can refer in terms of 2d plot(using 'text' function), but weirdly none about 3d plot...Please help me.
