One sample test

Hi all,
I would like to test the uniformity (or no uniformity) of  a vector field.
To do so, I would like to use a ks.test (Kolmogorov-Smirnov) but don't 
know what value to give for the second parameter in case of a one sample 
test, as it is my case here. An other question is, does any body know if 
there is a R function to perform a Kuiper test ?
Regards
