3.3 Bar chart: geom_bar()
- Makes a bar plot.
- What’s up with
stat = "identity"
?- The default stat is to count values.
- Setting this parameter leaves the data unchanged.
# Why, though? Perhaps I want to do my own aggregation
data_diamond_count <-
diamonds |>
count(cut, name = "count")
ggplot(data_diamond_count, aes(cut, count)) +
geom_bar(stat = "identity")
