[R] Print plot to pdf, jpg or any other format when using scatter3d error

[Jurica Seva]

Hi,

I have been trying to output my graphs to a file (jpeg, pdf, ps, it 
doesnt matter) but i cant seem to be able to get it to output. I tried a 
few things but none of them worked and am lost as what to do now. I am 
using the scatter3d function, and it prints out the graphs on tot he 
screen without any problems, but when it comes to writing them to a file 
i cant make it work. Is there any other way of producing 3dimensional 
graphs (they dont have to be rotatable/interactive after the print out)?

The code is fairly simple and is listed down :

#libraries
library(RMySQL)
library(rgl)
library(scatterplot3d)
library(Rcmdr)
