[R] Normal distribution test

[Markus Mehrwald]

Hi all,

I am completely new to R and my knowledge of statistics is quite small 
so I hope you can help my.
I have three dimensional point data which represents (and this is what I 
do not know for sure) a normal distribution. Now I want to test if this 
is true or not and as I can remember from statistics lessons I can use 
Chi-Square test for distribution test. BUT: I have realy no idea how to 
do this with R and additionally if my assumptions are correct and if 
this is possible with R at all.

Thank you very much in advance for any answer.
Markus
