Proposed Vignette: Additional PCA Plots

[bryanhanson]

Could create a new vignette with some additional PCA plots

• [ ] Plot 1 loading against another; include a circle with radius = 1 indicating that the maximum value of a load is +/- 1 since it is the cosine of an angle (and link back to "Understanding Scores and Loadings" vignette).
• [ ] Illustration/discussion of the biplot.

Brian Saulnier's data set has a good story built around a biplot. I'll give some thought to the loading vs loading plot as well.

Sounds good!
