This repository has teaching materials for a hands-on Introduction to R workshop. The workshop will introduce participants to 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 both basic R programming knowledge and its application for increasing efficiency for data analysis.

These materials are developed for a trainer-led workshop, but also amenable to self-guided learning.

1. R syntax: Understand the different 'parts of speech'.
2. Data types structures in R: Describe the various data types and data structures.
3. Data inspection and wrangling: Demonstrate the utilization of functions and indices to inspect and subset data from various data structures.
4. Visualizing data: Demonstrate the use of the ggplot2 package to create plots for easy data visualization.
