Graphing the "beavers" dataset using ggplot2
This is a workbook I put together for my own benefit while learning from Winston Chang's "R Graphics Cookbook," specifically Chapter 4 where line graphs are covered. The code in this document is all mine, except where cited from help documentation in one chunk. The "beavers" dataset is in the "datasets" library included with base R. For this workbook I basically restricted the data to the temperature variable plotted against the time increments. Scroll down to look at some results of experimentation with the geom_line(), geom_point(), and theme_***() functions.
