Dear S-plussers

After some time and frustrations, I now succeeded in making CVprobs work.
Excuses for any troubles that may have caused you.

The remaining question of the first email may be a non-Splus question:

I am still not sure about the best way of testing the fit of my cross-validated
predictions to my observed values. There is a lot of zeros in data and the
residuals do not seem to be normally distributed. I consider using a rank
correlation test (spearman or kendall), and it does seem to make sense. Is there
a better way?

Regards and happy christmas
