Sharon Machlis is a journalist with Computerworld, and to show other journalists how great R is for data visualization she shows them these five data visualizations, each of which can be created in 5 lines of R code or less.
I've reproduced Sharon's code and charts below. I did make a couple of tweaks to the code, though. I added a call to checkpoint("2016-08-22") which, if you've saved the code to a file, will install all the necessary packages for you. (I also verified that the code runs with package versions as of today's date, and if you're trying out this code at a later time it will continue to do so, thanks to checkpoint.) I also modified the data download code to make it work more easily on Windows. Here are the charts and code:
