Text data is everywhere, but it is rarely ready for analysis without significant cleaning and processing. This course teaches you how to confidently manipulate, extract, and clean textual information in R using the powerful stringr package. You will learn to transform raw, unstructured text into structured, analysis-ready formats.
By working through practical, text-based lessons, you will transition from manual data cleaning to writing efficient, automated text-processing workflows. You will gain a deep understanding of pattern matching and how to handle common data-cleaning headaches like irregular spacing, mixed casing, and hidden characters.
What you will learn:
- Understand the core principles of text processing and string behavior in R
- Clean and format messy text by managing whitespace, casing, and padding
- Extract specific substrings and patterns from complex text datasets
- Apply regular expressions (regex) within stringr functions for robust pattern matching
- Detect, locate, and replace target text elements across large datasets
- Combine stringr operations with modern tidyverse workflows for seamless data preparation
This course begins with foundational concepts, establishing essential terminology and string mechanics before moving on to practical text-matching techniques. You will read structured explanations, study clear code examples, and practice your skills with targeted written exercises.
This course is designed for beginners who have a basic familiarity with R and want to build essential data-cleaning skills. No prior experience with text mining or regular expressions is required.
