Hi - I created a "Comprehensive Graphics in R" course on Udemy with 500 free registrations available for any interested EDRESMETH people:
If you use R, or are curious about R, you might find this no-cost Udemy course useful. If you finish the course (there is no time limit) you earn a Certificate of Completion.
The course covers the 3 major R graphics systems: Base, GGplot and Lattice ("trellis") graphics and demonstrates how to create hundreds of different 2D and 3D graphical visualizations using your own research data.
The course is free, I won't even know the email address of anyone who grabs one of these 500 gift registrations.....please know that they all expire on February 29 (yes, this is a Leap Year) so grab one before then if you have any interest.
Best, Geoffrey Hubona Ph.D
