r-cran-markdown binary package in Ubuntu Bionic amd64

 Provides R bindings to the Sundown Markdown rendering library by
 Vicent Marti
 e.a., based upon work by Natacha Porté. Markdown is a plain-text
     formatting syntax that can be converted to XHTML or other formats.
 .
 The R function `markdownToHTML` renders a markdown file to HTML. Options
 controlling HTML output and supported markdown extensions can be
 optionally specified.
 .
 The package also exports the underlying Sundown C extension API which
 enables creating and calling custom renderers using the
 `renderMarkdown` function.
 .
 Please note: the rmarkdown package (with leading r) converts R Markdown
 documents into even more formats, by using pandoc; the CRAN rmarkdown
 package is a newer and enhanced version of this markdown package.
