You’ve mastered R’s data structures and know how to get data in and out. Now, it’s time to talk about what truly makes R a powerhouse: functions and packages! This is where R’s capabilities explode, allowing you to do almost anything with data.
In Part 3 of our R Programming series, our latest video, “Essential Functions & Packages: Expanding R’s Capabilities,” simplifies these critical concepts.
Functions: Your Code Superheroes
Think of functions as mini-programs that do specific jobs. Need to calculate an average? There’s a function for that (mean())! Want to round a number? Another function! We’ll show you how to use R’s built-in functions and even briefly how to write your own to automate tasks.
Packages: R’s App Store!
If functions are R’s built-in tools, then packages are like apps you download to supercharge R. Want to fetch live stock data? There’s a package (quantmod) for that! Need to create stunning charts? There’s another (ggplot2)!
In the video, you’ll learn:
- Why packages are absolutely essential.
- The simple steps to install a package (one-time job).
- How to load a package (every time you want to use it).
- A quick demo using
quantmod‘sgetSymbols()to download real financial data!
This video is your gateway to harnessing the incredible breadth of R’s capabilities. Get ready to expand your R toolkit significantly!
