Hi Dirk,

The use of Unit test framework in Rmetrics is rather recent and there 
are still room for a lot of improvement. For the moment we focus on 
tests which check if everything is running and we compare values where 
we do not need to set a  tolerance threshold. In the future we will 
check numerical results with tolerance and use the function 
checkEquals(). But for the moment we stick to checkIdentical().
