Levels for factors not clear #30

We assign "Female" first when setting the levels: levels(factor_survey_vector) <- c("Female", "Male") but "male" is the first factor: male <- factor_survey_vector[1]

This is because the first element of survey_vector is "M" Could this behavior be made clearer somehow?

It would be better to make this explicit by using

levels(x) <- c(F = "Female", M = "Male")
