[BioC] permutation test

[Patricia]

Hi,
My question is about the number of permutations in a randomization test. I
would need to make a very large number of permutations (around 10000) and I
can't find a function that calculates the pvalue from that.


Thanks

Patricia

Hi

I don't really understand your question but perhaps these functions may
help:

?sample
?combn

Hi everyone,

 

Is there any function to apply a randomization test (permutation test)
in witch you can choose the number of permutations?

I've using function perm.test but I need to make more permutations.

 

Thanks!

 

Regards

 

Patricia
