This git contains practice datasets for visualizing data with the R package ggplot2. Prior to working with this exercise, you should have the software R, available at http://cran.r-project.org/, and R Studio, available at www.rstudio.com Each product is open source software.
We will be using the graphics package ggplot2. To install it, click on the Package tab (lower right pane in R Studio), then click on Install and type "ggplot2" (without the quote marks). ggplot2 will then appear on the list of available packages. Click in the checkbox to load it in your workspace.
Each dataset is a CSV (comma-separated variable) that should be loaded into R prior to use. The files are:
