Histogram





Welcome to the histogram section of the R graph gallery. A histogram is used to study the distribution of one or several variables, as explained in data-to-viz.com. If you're looking for a simple way to implement it in R, pick an example below. This page focuses on ggplot2 but base R examples are also provided. This online course can be a great addition to know more about ggplot2.

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.
