You did not provide reproducible example nor structure of you data. From what you explain I think that problem can be in factors behaviour. Factors retain all levels until they are explicitly told to drop them. See ?factor Also your output from table is rather strange. Maybe table(factor(x.sub$RES_ID)) can help you. Without reproducible example it is difficult to evaluate your problem correctly.
