Dear Jason,
Yes, here is one way:
> a_tmp<-c("a", "b", "c", "d", "e", "f", "g", 'h')
> b_tmp<-c("a", "c", "e", "g")
> b_tmp %in% a_tmp
[1] TRUE TRUE TRUE TRUE
> b_tmp[b_tmp%in%a_tmp]
[1] "a" "c" "e" "g"
> all(b_tmp %in% a_tmp)
[1] TRUE
Take a look at ?"%in%" and ?all for more information.
HTH,
Jorge
