In the last movie, we looked at how you could use scatterplot matrices to show…the associations between several quantitative variables simultaneously by…creating a 2D matrix of scatterplots.…In this movie, I want to look at an interesting variation where you actually use…a 3D scatterplot that rotates in space with the mouse.…To do this, I'm going to use the data set google_correlate that I've used…for the other ones.…I'm going to load it on line 6.…Just get a list of names with line 7.…
Then there's actually several ways to do 3D scatterplots in R.…I'm going to be using the package rgl.…I've now downloaded it, and installed it.…Now I'm going to open it to run.…Then what I'm going to do is just run this one set of code.…plot3d is the function, and then you need to list the x, y, and z variables.…So, I've got them all as data_viz from the Google data set degree from the…Google data set, and Facebook.…Those are relative interest as search terms.…
Then I'm also adding labels for the x, y, and z axis.…
The course continues with examples on how to create charts and plots, check statistical assumptions and the reliability of your data, look for data outliers, and use other data analysis tools. Finally, learn how to get charts and tables out of R and share your results with presentations and web pages.
