markdown function

Insert inline Markdown

This function accepts Markdown-syntax text and returns HTML that may be included in Shiny UIs.

markdown(mds, extensions = TRUE, .noWS = NULL, ...)

Arguments

• mds: A character vector of Markdown source to convert to HTML. If the vector has more than one element, a single-element character vector of concatenated HTML is returned.
• extensions: Enable Github syntax extensions; defaults to TRUE.
• .noWS: Character vector used to omit some of the whitespace that would normally be written around generated HTML. Valid options include before, after, and outside (equivalent to before and end).
• ...: Additional arguments to pass to commonmark::markdown_html(). These arguments are dynamic.

Returns

a character vector marked as HTML.

Details

Leading whitespace is trimmed from Markdown text with glue::trim(). Whitespace trimming ensures Markdown is processed correctly even when the call to markdown() is indented within surrounding R code.

By default, Github extensions are enabled, but this can be disabled by passing extensions = FALSE.

Markdown rendering is performed by commonmark::markdown_html(). Additional arguments to markdown() are passed as arguments to markdown_html()

Examples

ui <- fluidPage(
  markdown("
    # Markdown Example

    This is a markdown paragraph, and will be contained within a `<p>` tag
    in the UI.

    The following is an unordered list, which will be represented in the UI as
    a `<ul>` with `<li>` children:

    * a bullet
    * another
