nomnoml with roxygen

[lschneiderbauer]

Hello!

I attempted to use nomnoml markdown commands in roxygen documentation, e.g. like this:

##' ...
##' @details
##' ## Graphical representation
##'
##' ```{nomnoml, testnomnoml, echo=FALSE}
##' #direction: down
##' #padding: 8
##' #spacing: 30
##'
##' [random_thing | another_random_thing]
##' ```

This almost worked:

• The generated .Rmd files use the wrong figure link:

\subsection{Graphical representation}{

\figure{man/figures/testnomnoml-1.png}
}

But it should be

\subsection{Graphical representation}{

\figure{testnomnoml-1.png}
}

since according to the R documentation they should be relative to the path "man/figures/".

• The generated figure's resolution is so low that the picture is barely recognizable. How can I change that?
• The figure seems to always be in the same format, no matter the actual content, so there sometimes is a lot of whitespace. Is it possible to crop the picture, so only the relevant pixels are included?

Is nomnoml intended to be used with roxygen? Or should I rather not attempt that at all?
Thank you for your help!
