Re: [R] Labelling individual points on 3D PCA scatterplot

Hello，I am a Chinese student, and I got the same problem. I have learnd R for several weeks, I want to draw a PCA picture. I have data in excel format like this: ID d1 d2 d3 d4 A 1234 B 1234 C 1234 D 1234 E 1234 How to load these dat

Re: [R] Labelling individual points on 3D PCA scatterplot

Thank you Duncan! That is very helpful, after posting this i did figure out how to convert the 2d coordinates into 3d. I was initially hesitant about using rgl because i thought it looked messy. With the modifications you suggested for the plot, it actually looks very clear now in rgl! And it rota
