Creating Workflow Vignettes

What is a workflow vignette?

Workflow vignettes are documents which describe a bioinformatics workflow that involves multiple Bioconductor packages. These workflows are usually more extensive than the vignettes that accompany individual Bioconductor packages.

Existing Workflow Vignettes

Workflow vignettes may deal with larger data sets and/or be more computationally intensive than typical Bioconductor package vignettes. For this reason, the automated builder that produces these vignettes does not have a time limit (in contrast to the Bioconductor package building system which will time out if package building takes too long).

Who should write a workflow vignette?

Anyone who is a bioinformatics domain expert.

How do I write a workflow vignette?

Using Math Symbols in a Markdown workflow vignette

If you want to include math symbols in a workflow vignette, put the following snippet at the beginning of your .Rmd file:

<script type="text/javascript"

Then you can use math the same way you would in LaTeX, except the symbols for escaping it are different. For inline formulae, use \\(N\\), and for displayed equations, use $$N$$.

The first will render as \(N\) and the second as .

Adding metadata to a Markdown vignette

With a markdown vignette (.Rmd file) you can add a YAML metadata preamble at the beginning of the file, for example:

Author: My Name
Date: March 16, 2015

This metadata will be rendered in the “About This Document” box that appears at the top of the web page.
