[Rd] vignette/knitr help

[Thierry Onkelinx]

Dear Mick,

Note that both knitr and rmarkdown are listed under Suggests: both are
required to compile the vignette. Installing rmarkdown should solve
the problem. If not, please provide more information. OS, R version,
digest version, ...

To call in the statistician after the experiment is done may be no
more than asking him to perform a post-mortem examination: he may be
able to say what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does
not ensure that a reasonable answer can be extracted from a given body
of data. ~ John Tukey
