Create a ranking variable with dplyr?

Other solution when you need to apply the rank to all variables (not just one).

df = data.frame(name = c("A","B","C","D"),
                score=c(10,10,9,8), score2 = c(5,1,9,2))

select(df, -name) %>% mutate_all(funs(dense_rank(desc(.))))

It sounds like you're looking for dense_rank from "dplyr" -- but applied in a reverse order than what rank normally does.

Try this:

df %>% mutate(rank = dense_rank(desc(score)))
#   name score rank
# 1    A    10    1
# 2    B    10    1
# 3    C     9    2
# 4    D     8    3
