I’m using the version of R that will used for the April exam and I’m using the Actex manual. I ran the chunk below, but not seeing any 3d scatter plot. I’ve tried uploading different packages, making my plot window bigger, but after running this chunk, *nothing* happens–no error messages, either.
install.packages(“car”)
install.packages(“rgl”)
library(car)
library(rgl)
scatter3d(sales ~ TV + radio, data = ad)
