Learn R

Why R?

  • Chance is that sooner or later, you’re going to use R, one of the (if not the) most popular statistical programming languages in the world. It’s not only that R is free which makes it so good, but because thousands of people across the world use it, document it, and develop it further.

    Warning

    The R interface may be scary at first sight, especially if you’re used to using Excel to do your data magic. But trust us, investing in learning R will pay off greatly. Not only for your career at grad school, but also for your career in industry. R (next to Python) has been a de-facto standard when applying for jobs in marketing analytics or data science.

  • One thing that’s great about R is that there are tons of resources available to learn it. Well - that brings the difficulty that you need to know which resources to use to learn it most efficiently.

Tip

Here are a few tips to learn R efficiently.

  • Have a project!

    “Huh - why to have a project? I first need to learn R!”

    Well, if you really want to learn R, then you should already have a project in mind that you would like to tackle. R is such a powerful tool that you would get entirely lost if you didn’t actually know what you would like to accomplish. If you don’t have a project, and still would like to learn R, we suggest you to do some googling for some interesting datasets to get you started (e.g., Kaggle.com).

  • Follow our R/R Studio installation guide

  • Enroll R courses at Datacamp.com (free-to-use with a Tilburg University account!)

    • Must do’s for novices
    • Must do’s if you have to manage data and prepare your own datasets
      • Learn data.table, our preferred tool to wrangle with large data. Just search for data.table at datacamp.com. These are our favorites courses: Data manipulation and Joining data.
      • Complementary to data.table, you should dive into Tidyverse, a collection of tools that will make your life much easier. This is our top-pick: Introduction to Tidyverse
    • Learning your method
      • As soon as your data is prepped, you can start analyzing. Of course, your method is informed by your specific research question. For most students, a refresher in regression analysis (e.g., OLS, Logit) may be exactly what they need.
