Data Analytics Workouts: Support Vector Machines on Big Five Traits and Politics
Working through a Pluralsight tutorial on Support Vector Machine, I adapted it to one of my usual data sets, Hofstede Cultural Dimension and Big Five state-level personality traits:

Data Analytics Workouts: Charting Correlation Matrices in R
I noticed this very simple, very powerful article by James Marquez, Seven Easy Graphs to Visualize Correlation Matrices in R
, in the Google+ community, R Programming for Data Analysis
, so thought to give it a try, since I started some of my current analyses a decade ago by generating correlation matrices in Excel, which I've sometimes redone and improved in R.

Data Analytics Workouts: Data Mining Explorations
Another Pluralsight training course, Data Mining Algorithms in SSAS, Excel, and R
, had one sections on Navie Bayes and on decision trees. I worked through the example, but varied using my own data and code, linked below.
