This course is open and free to all.
If you work with data and numerics in any fashion with R, it would help you to learn more about Multivariate Data Visualization using the lattice package in R. Deepayan Sarkar's excellent work porting over the "trellis graphics" capabilities from the S language developed originally in Bell Labs into the lattice package in R enables the rich, innovative and powerful visualizations of data in 2, 3, 4, or more dimensions through the use of conditioning and panel functions.
If you are a quantitative number-cruncher in any shape or form . . . student, professional, or faculty, you should take a look at the lattice package in R and consider registering for this no-cost online course.
