Pandoc ( to be distinguished from `pandoc()`) is an external-to-R software hammer capable of creating items of special beauty when supplied with dross text-materia.  `knitr` will be relying upon its availability when it casts its magical spells. `knitr` on CRAN is currently at version 1.11.

The incantations needed to acquire your very own pandoc hammer are in the link on that page entitled "Pandoc website".
