How to Open an .R File in RStudio (With Example)


An R file is a script written in the R programming language.

These files end with an .R extension. For example, an R script might be saved as my_script.R.

These files are typically used within RStudio, an interactive environment where you can work with R code.

The following example shows how to open an R script in RStudio in practice.

file.edit('my_script.R')
