Thanks, Peter. This has actually solved the problem.
I should have thought about this fix.
It surprises me that problems of this sort are not caught by the extensive
automatic checks which a package goes through when is submitted to CRAN.
Probably it happens because the only example within the CEoptim documentation
is quite basic, while the more substantial examples are in the accompanying
paper, but these are not checked by CRAN.
Best regards,
Adelchi
