exact values for p-values

there is no such thing as an "R lib".  
Do you mean "R package"?
Yes. I usually refer to them R packages as as libraries, hence the use 
of lib.

Regards. Stephen.
In any case, not it is not (yet).
As David clearly says (a few lines below), it is a 'f90'
library; which means it's "fortran 90" source code that you can
compile and then use.

I've tried with gfortran (the latest avaiable on debian amd64
sid) and it quickly ended in a compiler (!) error.

   S> if so which version? How/where can I  download it?

Netlib has all the TOMS (= Transactions Of Mathematical Software)
algorithms.  Look for '814'.

Regards,
Martin
