I was learning about geom_bar.
geom_col is a shortened version of geom_bar(stat = "identity"), and
It also sometimes plays the role of summarize.
However, reading the reference, I found out that geom_bar and geom_col are wrapper functions for stat_identity and stat_count.
Why is that?(why work as wrapper ?)
Is there a historical background?
Why don't geom_line and geom_violin have stat_*?
I asked this question out of intellectual curiosity.
Thanks for reading.
