for now this is a separate function internally but I feel like
between
should dispatch and deal with at leastREALSXP
,STRSXP
,INTSXP
andRAWSXP
.The string version uses a
VectorVisitorImpl<STRSXP>
so that it can take advantage of itsgreater
andless
methods.Wondering however if we could take advantage that the
vec
inVectorVisitorImpl<STRSXP>
is forced to be utf8, would we not have a way to compare two utf8 strings without having to go through the hoops ofCharacterVectorOrderer
