Many thanks for the help I received from people yesterday regarding vector 

I have a question regarding the Kolmogorov-Smirnov test.

I have a vector of 1000 numbers (called 'data') which I suspect to follow a 
chi-squared distribution with 9 df so I am running the command:

ks.test(data, "pchisq", df=9)

I am continually getting a p-value of  < 2.2e-16 which is leading to a 
continual conclusion that my numbers are not equal to the distribution being 

I have tried changing the number of df and although the value of D statistic 
changes (ranging from 0.2 to 1) I always get a p-value of < 2.2e-16 

What I am doing wrong here and is there any way to forc R to give me any more 
detail about the calculation it has carried out?

Thanks in advance
