How-To: Rstudio: Use Here Package for Platform Independent Relative Paths

Utilize relative and platform independent paths in your Rstudio project for portable code.

How do I make my Rstudio project platform independent and utilize relative paths for portability?

 

1. Create a new project with renv.

Example project: my_research_project

 

2. Install and load here package.

 

3. Build and use platform independent paths.

Example project directory structure: 

my_research_project/

│── my_research_project.Rproj

│── data/

│   └── raw_data.csv

└── scripts/

    └── analysis.R

Example R code snippet: 

library(here) # to setup path

library(readr) # to read csv file

# Build the path dynamically

data_path <- here("data", "raw_data.csv")

# Read the data

my_data <- read_csv(data_path)

 

4. data_path is now relative to my_research_project and platform independent. my_data will be populated with contents of raw_data.csv regardless of operating system.
