Description
This repository has teaching materials for a 2-3 hour, hands-on Introduction to R workshop led at a quick pace. The workshop will give participants an overview of the basics of R and RStudio. R is a simple programming environment that enables the effective handling of data, while providing excellent graphical support. RStudio is a tool that provides a user-friendly environment for working with R.
These materials are intended to provide a quick overview of the R programming language.
Learning Objectives
- R syntax: Understanding the different ‘parts of speech’ in R; introducing variables and functions, demonstrating how functions work, and modifying arguments for specific use cases.
- Data structures in R: Getting a handle on the classes of data structures and the types of data used by R.
- Data inspection and wrangling: Reading in data from files. Using indices and various functions to subset, merge, and create datasets.
- Exporting data: Generating new data tables for use outside of the R environment.
These materials are developed for a trainer-led workshop, but also amenable to self-guided learning.
