摘要：
A variety of modal logics based on the relevant logic R are presented. Models are given for each of these logics and completeness is shown. It is also shown that each of these logics admits Ackermann's rule gamma and as a corollary of this it is proved that each logic is a conservative extension of its counterpart based on classical logic, hence we call them ''classically complete''.
