Examples

library(dplyr)
colon_s %>% 
  summarise(age.factor = ff_mode(age.factor))
  
colon_s %>% 
  select(sex.factor, rx.factor, obstruct.factor, perfor.factor) %>% 
  summarise(across(everything(), ff_mode))
  
colon_s %>% 
  reframe(across(where(is.factor), ff_mode))
  # Note, 4 rows is returned in this example because 4 factor levels within `hospital` 
  # have the same frequency.
