Installing R and RStudio

Before using R, learners need to understand the relationship between R and RStudio. R is the language and computational engine. RStudio is an integrated development environment that makes it easier to write, run, organize, and review R code. R can be used without RStudio, but RStudio provides a more user-friendly interface for beginners and is widely used in academic and applied research settings [@posit2024rstudio].
