Raw output via raw_text()

raw_text() writes text to the output verbatim (interpreted as Markdown), so you can mix normal output with raw output in the same code chunk without setting results = 'asis' for the whole chunk:

1 + 1  # normal verbatim output

#> [1] 2

litedown::raw_text(c('A **raw** Markdown paragraph, e.g.,',
  'a bullet list:', '', '- one', '- two'))

A raw Markdown paragraph, e.g., a bullet list:

• one
• two

With the format argument, the text is wrapped in a raw block that only appears in the corresponding output format:

litedown::raw_text('<span style="color: red;">Red (HTML only).</span>', 'html')

Red (HTML only).
