Introduction to ggplot2
March 7, 2017 @ 9:00 am - 12:00 pm
This workshop introduces how to use the R ggplot2 package, particularly for data analysis accompanying a planned regression model.

Then the usage of ggplot2 for exploratory graphs, model diagnostics, and presentation of model results is illustrated through 3 examples.
