Description Usage Arguments Details Value Examples

View source: R/rmdcount.R

Counts words, characters and non-whitespace characters in R Markdown files.

1	rmdcount(files = NULL, space = "[[:space:]]", word = "[[:space:]]+")

`files`	character: file name(s)
`space`	character: pattern to split a text at spaces (default: `'[[:space:]]'`)
`word`	character: pattern to split a text at word boundaries (default: `'[[:space:]]+'`)

It uses the following approaches to detect words, characters and non-whitespace characters.

words: strsplit(rmd, word)[[1]] with word equal to '[[:space:]]+'
characters: strsplit(rmd, '')[[1]]
non-whitespace characters: strsplit(gsub(space, '', rmd), '')[[1]] with space equal to '[[:space:]]'

This is repeated for the text without code chunks. Code chunks are deleted with gsub('```\\{.*?```', '', rmd).

chars_chunk: number of characters excluding code chunks
nonws_chunk: number of non-whitespace characters excluding code chunks
path: path of a file
