Dear List,

Rather a basic question, and it may have been answered, but I couldn't
find anything in the archives.

I'm wondering if I can say "not R.C" (where R and C are a role and class
respectively). I'm trying to express a concept such as "doesn't have
treatment with tamoxifen", so I'm not really looking for the complement
of R, just a way of expressing that the relationship R.C won't hold for
a particular individual.

Thanks a lot,

Matt
