Data visualization is an integral part of data exploration and presentation. Yesterday, we talked about ggplot2, a package which provides a mature and consistent system for plotting in R.
We explored the advantage and disadvantages of ggplot2, the syntax and usage of the package.
As always, thank you to everyone who showed up.
Materials I used for the open lab can be found here.
