Hello,

I want to show pca in three dimension with pca3d. It said "Creating new device". I am working in

yueli@yueli-ThinkStation-P330:~$ cat /proc/version
Linux version 5.11.0-40-generic (buildd@lgw01-amd64-010) (gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0, 
GNU ld (GNU Binutils for Ubuntu) 2.34) #44~20.04.2-Ubuntu SMP Tue Oct 26 18:07:44 UTC 2021

Thank you in advance for great help!

Best,
Yue

library(pca3d)
library(rgl)
data( metabo )
 pca <- prcomp( metabo[,-1], scale.= TRUE )
pca3d( pca, group= metabo[,1], 
        fancy= TRUE, bg= "black", 
      axes.color= "white", new= TRUE )
[1] 0.3439618 0.4500414 0.2818377
Creating new device

I also tried:

plot3d(iris)
