WebThe problem is that the levels are ordered according to the alphabetical order of the categories of ses.Thus, “high” is the lowest level of ses.f.bad.order, “middle” is the middle level and “low” is the highest level.In order to fix the ordering we need to use the levels argument to indicate the correct ordering of the categories. Let’s create a new factor … WebR uses factors to handle categorical variables, variables that have a fixed and known set of possible values. Factors are also helpful for reordering character vectors to improve display.
