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.


# where am I in my computer?
here()

"C:/Users/some/path/or/other"

#
# create a folder
dir.create(here("img"))
"C:/Users/some/path/or/other/img"

dir.create(here("img","png"))
"C:/Users/some/path/or/other/img/png"


#move to the outputs folder using setwd()
setwd(here("img"))

# check this worked - get the current working directory with  getwd()
getwd()

"C:/Users/some/path/or/other/img"

# go back to the root of the project
setwd(here())

#check you are back where you started

getwd()

"C:/Users/some/path/or/other"

Now the next time I am like this:

¯_(ヅ)_/¯

I can just read this post, and hope no-one sees me reading my own blog.
