Examples

# NOT RUN {
ar1 = ar_new(c("a", "b"), levels=c(2, 3))
ar2 = ar_new(c("c", "a"), levels=c(2, 2))
ar1
ar2
## dimension a has levels a1,a2 in both ar1 and ar2.
# Hence we have a match.
dimnames_match(ar1, ar2)

ar1 = ar_new(c("a", "b"), levels=c(2, 3))
ar2 = ar_new(c("c", "a"), levels=c(2, 3))
ar1
ar2
## dimension a has levels a1,a2 in ar1 and levels a1,a2,a3 in ar2.
# Hence we do not have a match.
dimnames_match(ar1, ar2)

ar2 = ar_new(c("c", "a"), levels=list(c=c("c1", "c2"), a=c("a2", "a1")))
ar2
## dimension a has levels a1,a2 in ar1 and levels a2,a1 in ar2.
# Hence we do not have a match.
dimnames_match(ar1, ar2)
# }
