• 2 TL;DR

Problem: You want to read in a data file in an R code chunk in an R Markdown post. But:

• Where should you save the data file?
• What file path will work to run the code chunks in the console?
• What file path will work when you serve site?

Solution: Read on.

This post will show you how to add local data files to your blogdown site, and the file paths to read those data files in an R code chunk. (If you came here looking for how to add static images and use file paths, please see this post.)

Let’s say you have a data file called 'mazes.csv', and you want to read in that CSV file in an R chunk. The below table summarizes where the file should live in your blogdown site directory, and the file paths to use.

More detail on each of these scenarios below. We’ll use readr::read_csv(), so you’ll need to install and load the readr package:

2.1 Place file in your post/ folder

What to do:

• File goes in /content/post/mazes.csv
• R file path is 'mazes.csv'

Example:

2.2 Place file in your static/ folder

What to do:

• File goes in /static/mazes.csv
• R file path is '../../static/mazes.csv'
• R file path with here is: here('static', 'mazes.csv')

Example:

2.3 Place file in your static/data/ folder

R Markdown Examples

What to do:

• File goes in /static/data/mazes.csv
• R file path is '../../static/data/mazes.csv'
• R file path with here is: here('static', 'data', 'mazes.csv')

Example:

2.4 Place 'mazes.csv' online

What to do:

• File goes online: options include in a GitHub gist or push to your site’s repo
• Use the raw GitHub or gist url

Example:
