Notes on the here package –
The here package is pretty simple ( only 3 functions), but I cannot remember how to use it to navigate folders, so this is my aide-memoire.
It might be useful for others too.
Here finds the root of your current folder / working directory.
If you use Projects in RStudio, that will usually be the root of your project folder.
If not, you can use set_here() to create a small file which will set the root location.
