What is R?

• A programming language
• Focus on statistical modeling and data analysis
• Useful for epidemiology, biostatistics, and data science
• Great visualizations

What is RStudio?

Modern Dive

• R is a programming language

• RStudio is an integrated development environment (IDE)
  
  • An interface to use R (with perks!)

We open RStudio on our computer (not R!)

If you have issues downloading on your laptop for in-class use

• There is a really cool online interface that will be sufficient for our in-class use!

• https://posit.cloud/

  • If you Google “Posit cloud” it should come up easily

• I don’t recommend this for homework use (once we get to it)

So let’s take some time to download each!

• Use this link to start: https://posit.co/download/rstudio-desktop/
• I will click on this link!

 

• You must install R first
  • Even if you have R installed already, I highly recommend installing the latest version
  • In the future, you will periodically want to update this
• Install RStudio Desktop Open Source License (second)

 

• If you get them both installed, then you can open up RStudio and start checking it out
