Docco

To use the Docco style for Markdown vignettes in an R package, you need to

• add*.Rmd files under thevignettes directory
• addSuggests: knitr andVignetteBuilder: knitr to theDESCRIPTION file
• specify the vignette engine\VignetteEngine{knitr::docco_classic} in theRmd files (inside HTML comments)

After building and installing the package, you can view vignettes via

browseVignettes(package = 'Your_Package')

Examples

Below are some code chunks as examples.

cat('_hello_ **markdown**!', '\n')

hellomarkdown!

Normally you do not need any chunk options.

1+1

## [1] 2

10:1

##  [1] 10  9  8  7  6  5  4  3  2  1

rnorm(5)^2

## [1] 0.93675 1.62965 0.05061 0.10361 2.21366

strsplit('hello, markdown vignettes', '')

## [[1]]##  [1] "h" "e" "l" "l" "o" "," " " "m" "a" "r" "k" "d" "o" "w" "n" " " "v" "i" "g"## [20] "n" "e" "t" "t" "e" "s"

Feel free to draw beautiful plots and write math \(P(X>x)=\alpha/2\).

n=300; set.seed(123)par(mar=c(4,4,.1,.1))plot(rnorm(n), rnorm(n), pch=21, cex=5*runif(n), col='white', bg='gray')

How does it work

Custom CSS and JS files are passed tomarkdown::mark_html() to style the HTML page:

knitr::rocco

## function (input, ...) ## {##     knit2html(input, ..., meta = list(css = c("@npm/@xiee/utils/css/docco-classic.min.css", ##         "@prism-xcode"), js = c("@npm/jquery@3.7.1/dist/jquery.min.js", ##         "@npm/@xiee/utils/js/docco-classic.min.js,docco-resize.js", ##         "@npm/@xiee/utils/js/center-img.min.js")))## }## <bytecode: 0x13e5fcd98>## <environment: namespace:knitr>

That is it.
