Relative and Absolute Paths

How to Read This Project Structure:

/home/data_scientist/work/ is the parent directory on the computer.
climate_analysis/ is the main project folder.
The project has several subdirectories:
- src/ contains R scripts, including main.R and a helpers/ subdirectory.
- data/ has raw/ and processed/ subdirectories for data at different stages.
- results/ contains figures/ and reports/ for output.
Indentation shows the nested structure of directories and files.
