Ggplot2
Histograms can be built with ggplot2 thanks to the
geom_histogram() function. It requires only 1 numeric
variable as input. This function automatically cut the variable in
bins and count the number of data point per bin. Remember to try
different bin size
using the binwidth argument.
Base R
Of course it is possible to build high quality histograms without
ggplot2 or the tidyverse. Here are a few
examples illustrating how to proceed.
