How to change facet labels?

Question

I have used the following ggplot command:

ggplot(survey, aes(x = age)) + stat_bin(aes(n = nrow(h3), y = ..count.. / n), binwidth = 10)
  + scale         


        

Answer 1

I think all other solutions are really helpful to do this, but there is yet another way.

I assume:

• you have installed the dplyr package, which has the convenient mutate command, and

• your dataset is named survey.

  survey %>% mutate(Hosp1 = Hospital1, Hosp2 = Hospital2,........)

This command helps you to rename columns, yet all other columns are kept.

Then do the same facet_wrap, you are fine now.
