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.
R programming allows us to create bar charts in a variety of ways. The standard function in R is the
barplot function. The
barplot function only requires a list of the heights to be displayed. All of the following parameters are optional.
The various parameters are as follows:
height, width = 1, space = NULL, names.arg = NULL, legend.text = NULL, beside = FALSE, horiz = FALSE, density = NULL, angle = 45, col = NULL, border = par("fg"), main = NULL, sub = NULL, xlab = NULL, ylab = NULL, xlim = NULL...
