Hi Sarah Goslee

Thanking you for replying to my doubt.

I downloaded the multtest package from CRAN and also went through the
package specific PDF file, they have given a list of functions which
includes the mt.transformV, mt.checkothers etc, that I am trying to access
which they call as the internal functions and say that these set of
functions cannot be called by the user. and these functions perform the
permutation part, so I need to somehow access them.

Regards
Ap
