Histograms in R: (R Tutorial 2.3)
In this video, you will learn how to produce histograms in R modify the histogram to better present your data.
First you will learn what a histogram is and when it is appropriate to use a histogram for your data. Then you will see how to produce a histogram in R using the "hist" command and modify it from the default options in R. For example, you will learn to change the y-axis to represent a probability density rather than frequencies using "freq" argument or "prob" argument, change the x or y limits of a histogram in R using the "xlim" or "ylim" argument, and change the bin width using the "breaks" argument. In this tutorial we will also show you how to add a title to a histogram using "main" argument, add labels to the x-axis or y-axis using "xlab" or "ylab" arguments, rotate the values on the y-axis of a histogram using the "las" argument, add a density curve using "lines" command, change the color of the density curve in the histogram using "col" argument and finally change the width of the density curve in a histogram in R using the "lwd" argument.
