Introduction to R Programming

Welcome to the OARC Introduction to R Programming Seminar!

This seminar assumes you have both R and RStudio installed.

This seminar is an introduction to R as a programming language. The aim of this workshop is to improve programming skills of R users who have some familiarity with R as a statistical package and would like to extend their R skills. We will talk about how R users can write functions to replace repetitive code and loops to iterate over the same algorithm repeatedly.

The slides for seminar can be found here: Introduction to R Programming
