The 'quadprog' pkg is not listed as a dependency or even as 'suggested' and there is no mention of 'quadprog' in the NEWS file, nor does a search of the 'demos' code for a call to load "quadprog" produce a hit, and there is no mention of quadprog in the NAMESPACE file, so the message while "clear" can still be considered "quite unexpected". -- David. > > Hope this helps, > > Rui Barradas > > Em 28-04-2015 20:32, Olufemi Bolarinwa escreveu: >> Hello,I tried installing optimx and got a confirmation that it was >> installed.
