Hi all, 

 

I am trying to test wheater the distribution of my samples is normal with QQ plot. 

 

I have a values of water content in clays in around few hundred samples. Is the code :

 

qqnorm(w)      #w being water content

qqline(w)

 

 

sufficient? 

 

How do I know when I get the plots which distribution is normal and which is not? 

 

Thanks, m
