R Programming for Data Analysis and Reports

Introduction

Why this course

Build introductory R skills for statistics and data analysis, from objects and functions to data frames, charts and a simple regression example. The two-day sequence also introduces generating Markdown-based reports to communicate code, results and narrative.

Learning outcomes

Use R data types, vectors, matrices, lists and indexing.
Write conditions, loops and user-defined functions.
Import, clean, transform, sample and export data frames.
Create introductory ggplot2 charts.
Fit and interpret a simple linear model, distinguishing correlation from regression.
Generate a basic Markdown-based analysis report.

Prerequisites

No prior R experience is required. Basic computer/file skills are useful. Use a supported R and RStudio Desktop environment on a compatible Windows, macOS or Linux system, selected packages and prepared datasets.
