[R] substituting own test statistics in a built-in function

Hi All

I would like to compute the raw p-value from permutation tests and I found
mt.sample.rawp() from the package multtest almost similar to what I want to
do. But in the function definition:

mt.sample.rawp(V,classlabel,test="t",side="abs",fixed.seed.sampling="y",B=10000,na=.mt.naNUM,nonpara="n") 
 
I would like to choose my own t-test which is designed using my model
parameters, so it is like a modification of t-test. I would like to use this
t-test instead of the ones in the list.  I am not sure if this can be done.
Can anyone tell me how to do it, if it is possible.

the other way I tried is to copy the function and and modify it. But it uses
internal functions from the package like mt.checkothers() which I do not
know perform what kind of function. I tried to access its function
definition, but I was not able to do so. is there some other way I could see
what these internal functions do, so that I could possibly try to use the
same logic and write the code. 

Appreciate all help. Thanks a lot :)

Regards
Ap
