In this section, I will show you how to generate bar charts and bar plots using R. I think whether you call a particular graphic a bar chart or a bar plot is up to you. There are minor differences between bar charts and bar plots. In both cases, we have bars representing counts; we display them across your graphic. The steps (and results) involved are similar.
