w      <- c(0L, NA_integer_, 22:25, NA_integer_, 40)
breaks <- c(0, 25, 50)
labels <- c("lower", "upper")

cut_with_nas(w, breaks=2)
cut_with_nas(w, breaks=breaks, labels=labels)
cut_with_nas(w, breaks=breaks               )
cut_with_nas(w, breaks=breaks               , include.lowest=TRUE)
cut_with_nas(w, breaks=breaks               , include.lowest=TRUE, right=FALSE)
cut_with_nas(w, breaks=breaks                                    , right=FALSE)
