build_snippet: Knit a single .Rmd snippet

In dgrtwo/rgallery: Build a Gallery of R Snippets

Description

Knit a .Rmd snippet into a .md file. A snippet is like a "mini-vignette"

Usage

build_snippet(input, output, base_url = "/", category = NULL, fig.path, ...)

Arguments

input	a .Rmd file to compile
output	the .md file to write
base_url	base_url of site
category	snippet's category
fig.path	directory where figures will be stored
...	extra arguments for knitr's chunk options, such as cache = TRUE

Details

This makes sure in the process that the images go into an accessible directory, and add an "image:" tag to the front-matter displaying one of the snippet's images (to use as a teaser on the main gallery page)
