11.32 Labels with Comma
%>% ds ggplot(aes(wind_dir_9am, fill=wind_dir_9am)) + geom_bar() + scale_y_continuous(labels=comma) + theme(legend.position="none") + labs(x=vnames["wind_dir_9am"], y="Count")
With ggplot2 (Wickham, Chang, et al. 2023) Version 0.9.0 the package introduced a mechanism to handle many of the scale operations, in such a way as to support base and lattice graphics, as well as graphics. Scale operations include position guides, as in the axes, and aesthetic guides, as in the legend.
The function scales::comma() is useful for presenting numbers
using commas to separate the thousands. This is always a good
idea as it assists the reader in quickly determining the magnitude of
the numbers we are looking at. As a matter of course, I recommend
commas in plots (and tables) at all times. To do so use the
ggplot2::scale_continuous() function with
