The goal of namer is to name the chunks of R Markdown files. It’s your safety net when you’ve (willingly) forgotten to name most chunks of all R Markdown files in a folder. namer does not give meaningful labels to your chunks, but it gives them labels that won’t change depending on their position like the automatic knitr:::unnamed_chunk function does when knitting. So you can e.g. shuffle your chunks and not loose their cache, or more easily debug over a whole folder!

For context about why you should name your R Markdown chunks, read this blog post.

The screenshot below is a real life example, result of running namer::name_dir_chunks("pres"). In each of the files in the dir “pres”, it labelled chunks using the filename and numbers.

Example of use

Installation

Install the dev version from this repo using:

remotes::install_github("lockedata/namer")

Use

This is a basic example which shows you how to solve a common problem. The “test” folder first contains R Markdown files with unnamed chunks. After running name_dir_chunks, they’re all named, with names using the filenames as basis.

fs::dir_copy(system.file("examples", package = "namer"),
            "test")
name_dir_chunks("test")
file.edit("test/example1.Rmd")

There’s also name_chunks for use on a single R Markdown file; and unname_all_chunks to unname all chunks of a single R Markdown file which can be useful when cleaning your chunk labels.

If you’re working with RStudio, installing the package will have installed an addin for labelling chunks of any R Markdown document you select.

When using namer, please check the edits before pushing them to your code base. Such automatic chunk labelling is best paired with version control.
