Summary: Extend the knitr package for better applications in the web so that web pages can be easily compiled with R like Sweave documents.
Description: The knitr package is a general-purpose tool for dynamic report generation; the basic idea is like Sweave: we only write source code in a document mixed with normal texts, then use a tool to evaluate the code to get output, so that we do not need to copy and paste results from the computing engine to the output document. Knitr comes with a flexible design and can be extended to multiple output formats via output hooks. Currently the LaTeX and Markdown support is almost complete, and HTML is not yet fully supported. Two missing features are code highlighting themes and animation support (both have been done for LaTeX).
The first part of this project is to add the missing features in HTML, which involve with CSS and the R package animation (function
saveHTML()). After this is done, the old wiki site of the animation package can be rewritten with knitr. Each page is written with R source code mixed with HTML or Markdown, then compiled to the final output containing animations. This will be easier to validate if the animation package works correctly and the animations can be reproducible. Depending on the progress, not all pages have to be converted in this project. The expected time span on this part is one month.
The second part focuses on online collaboration of reproducible research. We will explore two possible directions:
This part is also expected to be done in a month.
The third part is not completely decided yet: we can either see if the work can be applied to other websites like R Graph Gallery, or go to another direction – convert R package documentation to better web pages.
Test: Read the minimal demos in the knitr website, and use the knitr package to write a small report in HTML with a dataset (must contain plots; a few paragraphs will be enough).
