Advanced R Programming

Course Level: Advanced

This is a two-day intensive course on advanced R programming. The training course will not only cover advanced R programming techniques, such as S3/S4 objects, reference classes and function closures, we will spend a significant time discussing why and where these methods are used. The course will be a mixture of lectures and computer practicals. By the end of the course, participants will be able to use OOP within there own code.

Learning Outcomes

By the end of the day participants will…

  • be able to write scripts/functions in a more productive manner using environments, mutable states and R’s scoping rules
  • make their R session as efficient as possible on startup using the .Rprofile and .Renviron files
  • be able to use object oriented programming to their advantage
  • have the skill to use s3 & s4 class objects efficiently and effectively in their own work
