This is a quick tip to avoid having to use the setwd() function to set your working directory all the time.
Assuming you are working on a PC using RStudio, here is how to change your working directory to a R sub-folder. To do this, I made use of this guide.
Step 1: Go to C:\Program Files\R\[your_version]\etc
In here you will find a file called ‘Rprofile.site’.
Step 2: Open this file in a text editor
It should have a number of options pre-loaded.
Step 3: Add a new command at the bottom
It should say something like the following, depending how your files are stored:
setwd("C:/Users/[user]/Documents/R")
Step 4: Restart RStudio
Step 5: run the getwd() function
It should change to your new directory!
