[R] Importance of levels in a factor variable

I have a dataset of multiple variables and a response. For example, > str(x) 'data.frame': 3557238 obs. of 44 variables: $ response : Factor w/ 2 levels $ var2: Factor w/5000 levels If var2 for example is a factor with 5000 levels, what is the best approach to determine which of these level
