Failure to recode levels of a factor with dplyr mutate() and recode_factor

I have:

library(tidyverse)
mood <- 
  tibble(cond = factor(c('pl', 'nu', 'un')), rating = 1:3)

I would like to mutate mood into:

moodWish <-
  tibble(cond = factor(c('P', 'N', 'U')), rating = 1:3)

I tried:

mood1 <- mood %>%
  mutate(cond = recode_factor(cond,
                              'P' = 'pl',
                              'N' = 'nu',
                              'U' = 'un'))

I know that recode_factor is doing something, because it changes the order of the levels of cond but not the levels.

"When named, the argument names should be the current values to be replaced, and the argument values should be the new (replacement) values."

> mood1 <- mood %>%
    mutate(cond = recode_factor(cond,
                                'pl' = 'P',
                                'nu' = 'N',
                                'un' = 'U'))

> mood1
# A tibble: 3 x 2
  cond  rating
  <fct>  <int>
1 P          1
2 N          2
3 U          3
