AI Wrote Your R Code… But Do You Understand It?

Dare u to like comment and subscribe. Im doing my best here AI can write R code for you — but if you do not understand what the script is doing, you can easily make silent mistakes. This beginner-friendly R crash course is made for students, researchers, clinicians, and anyone who has started using ChatGPT, NotebookLM, or other AI tools to generate R code. Instead of just copy-pasting scripts, this video teaches the mental model behind R: objects, functions, data frames, missing values, transformations, plots, basic statistics, and how to check AI-generated code safely. In this video, you’ll learn: - How R actually thinks: objects, functions, and data frames - Why RStudio projects and scripts matter for reproducibility - How data frames work like strict research tables - How to understand rows, columns, variables, and missing values - Why `NA` is not the same as zero - How `ggplot2` builds plots - How to avoid silent mistakes in AI-generated R code - How to inspect your data before trusting any analysis This is not a complete advanced R course. It is a practical beginner lesson designed to help you stop blindly running code and start understanding what your R scripts are doing.
