Data Importing and Tidying in R for Clean Analysis

Real-world data is rarely clean, organized, or ready for analysis. Acquiring the skills to import, reshape, and tidy messy datasets is the most critical first step for any aspiring data professional. This text-based course guides you from raw, unstructured files to pristine, analysis-ready data structures using R. You will gain the confidence to handle diverse file formats, restructure complex tables, and build automated cleaning pipelines that ensure your work is reproducible and robust. What you'll learn: Understand foundational data structures and tidy data principles in R; Import data from diverse sources including CSV, Excel, and basic web scraping while respecting ethical guidelines; Clean and transform datasets using dplyr and modern Tidyverse workflows; Reshape and pivot complex tables with tidyr to prepare them for visualization; Build reproducible data pipelines using the modern native pipe operator; Manage project dependencies and environments to ensure your analysis remains reliable over time. The course starts with essential terminology and the philosophy of tidy data before moving into hands-on importing techniques. You will then progress through step-by-step restructuring exercises and practical cleaning workflows designed to tackle real-world data challenges. This course is designed for beginners who want to work with data in R, and no prior data cleaning experience is required.
