Steven Sanderson divvies out buckets for a histogram:
Histograms divide data into bins, or intervals, and then count how many data points fall into each bin. The
breaks
parameter in R allows you to control how these bins are defined. By specifying breaks thoughtfully, you can highlight specific patterns and nuances in your data.
Click through to see how you can use the breaks parameter in a few different ways to customize your histogram. The default breaks in R are often reasonable, but trying a few different breaks can help you get a better understanding of the actual distribution of the data.
