To allow for future changes in the way the need for duplication is detected in R internal C code, package C code should avoid direct use of NAMED,and SET_NAMED, or assumptions on the maximal value of NAMED. Use the macros MAYBE_REFERENCED, MAYBE_SHARED, and MARK_NOT_MUTABLE instead. These currently correspond to
MAYBE_REFERENCED(x): NAMED(x) > 0 MAYBE_SHARED(x): NAMED(x) > 1 MARK_NOT_MUTABLE(x): SET_NAMED(c, NAMEDMAX) Best, luke -- Luke Tierney Ralph E.
