In today's blog post, I introduce the `grep()` function in R, a key tool for searching patterns in text data.

It allows case-sensitive searches by default but can perform case-insensitive searches with the `ignore.case` argument.

This flexibility is essential for text mining, data cleaning, and analysis. I outline the basic syntax, usage examples, and common mistakes.
