SQL, R, Excel Cheatsheet

If you’re an aspiring data analyst, you’ll quickly realize most real-world work happens in three tools: SQL, Excel, and R.

This cheat sheet helps you connect the dots by showing the same core tasks (filtering, sorting, grouping, joining, handling missing values, and more) side-by-side across all three so you can:

• move across tools

• reduce mistakes

• stop wasting time Googling syntax

And if you’re already working as an analyst, this is the perfect quick refresher to save time when you blank on syntax or just want the fastest reference while you work.
