Module 5: Advanced Graphing in R

This video covers some more advanced plotting skills (expected to follow Activity #2 where you learn basic skills on your own). You will learn how to plot on two y-axes, write plots to a file, and make multi-panel plots. We will once again revisit the body fat data.

Video #4

For this video we will be working with the BodyFat.csv dataset again.

IF you are well practiced with reading data into R, feel free to read in our existing data object.

Make an R Notebook for this walk through tutorial to save all the code you will be learning. We will cover:

• Adding text to plots
• Plotting on multiple Axes
• Adding figure legends
• Making multi-panel plots
• Adjusting figure margins
• Writing images to a file
• Paralleling base R code to ggplot2 syntax to accomplish the same goals

Walk-through code

• R Markdown from video (Slideshow)

Data Files

• BodyFat.csv

Output PDF

• Body_Fat.PDF

Associated code and data files are also within the compressed data file.
