Is there any built-in way to lexicographically compare two vectors of
the same length in R? The textbook algorithm could be coded as follows:
lex.cmp <- function (vec1,vec2) {
for (j in 1:length(vec1)) {
if (vec1[j] < vec2[j]) { return(-1) }
if (vec1[j] > vec2[j]) { return(1) }
}
return(0)
}
Thanks,
Gabriel
