[R] Failing to install the rgl package

[Tunga Kantarcı]

Hi,

I try to execute the seven lines of code below to plot a graph. But I
am failing as the messages below show. Where am I going wrong?


install.packages("rgl")
library(rgl)
y_hat = X%*%B_hat
open3d(windowRect = c(100,100,900,900),family = "serif")
color = rainbow(length(y_hat))[rank(y_hat)]
plot3d(educ,exper,wage,col = color,type = "s",size = 0.5,xlim =
c(0,20),ylim = c(0,60),zlim = c(-10,70),box = FALSE,axes = TRUE)
planes3d(B_hat[2],B_hat[3],-1,B_hat[1],alpha = 0.5,col = "azure")
