Any sorting of input text file do not change factor levels ordering in R which is by default alphabetic. Do not guess how the language works, learn the rules from documentation and help pages. If you learned some foreign language you need to know some vocabulary and grammar to express understandable thoughts. And mostly people are more intelligent than computers when dealing with incomplete and twisted sentences.
