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.
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_chunks() to unname all chunks of
a single R Markdown file as well as unname_dir_chunks() to
unname all chunks of all R Markdown files in a directory, which can be
useful when cleaning your chunk labels.
By default unname_chunks() unnames all chunks with
exception of the ‘setup’ chunk. By using the argument
chunk_name_prefix one can indicate the prefix of the labels
that will be unnamed. Useful when one refers to a label by using chunk
option ref.label so that it is inconvenient when that label
is unnamed. By setting chunk_name_prefix equal to ‘the
filename with extension stripped’ followed with a ‘-’ (dash) only the
labels generated by name_chunks() will be unnamed.
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.
These binaries (installable software) and packages are in development.
