Vector-valued logicals in flow control constructions have gone through an elborate deprecation process before getting turned into errors.

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
