Orientating to R's ggplot2 for powerful multivariate data visualizations
- [Instructor] Okay, here we are in RStudio and what I'm going to walk you through is how to make this graphic. Now, before I begin, let me caution you, this graphic is a little busy. This is not something you would rush to put on an executive dashboard but our priorities are different. We are focused on finding out what's going on in the data. And often that means we have to look at a lot of variables at once and this graphic has four variables in it. Now ggplot2 can make beautiful graphics but again, we're focused on getting the information content out and that means looking at outliers and so on. So this might look a bit cluttered to you but it's because our goals are different than executive reporting. So here we go. To get the data in, you're going to need a command, something like this. And we're going to call the data census while we're in RStudio. Now, please be careful. Your path might not be…
