Object Oriented Programming in R
Course Level: Advanced (6 hours)
The training course will cover R object-oriented programming techniques. We’ll discuss what OOP is and the different varieties within R. Beginning with the popular S3 and S4 OOP frameworks, we’ll finish with the new {R6} package that is used extensively in Shiny applications. By the end of the course, participants will be able to use OOP within their own code.
