The knitr package version 0.5 is on CRAN now. It has gone through extensive development in the past few months, and about 200 issues were solved (https://github.com/yihui/knitr/issues) thanks to the feedback of users, which greatly improved the quality and usefulness of this package. For a complete list of changes, see https://github.com/yihui/knitr/blob/master/NEWS Most notable new features are: - chunk options can be arbitrary valid R code, e.g. <<echo=!TRUE, results=ifelse(x, 'asis', 'markup')>>=; this makes a document really programmable, and the syntax is also consistent with normal R code; http://yihui.name/knitr/demo/sweave/ - the listings package is supported via render_listings(), and the styles are based on Sweavel.sty (courtesy of Frank Harrell); http://yihui.name/knitr/demo/listings/ - for HTML/markdown documents, R plots can be automatically uploaded to Imgur to make sure the output is self-contained (no need to copy images when publishing the output); http://yihui.name/knitr/demo/upload/ - arbitrary recursive references of code chunks with <<label>> (e.g. chunk A can call chunk B which in turn calls C); http://yihui.name/knitr/demo/reference/ - for cached chunks, their dependencies can be automatically figured out by analyzing the R code for global and local variables (see the 'autodep' option) - new chunk options fig.cap and fig.scap to create figure environments with captions in LaTeX; - Sweave concordance was implemented and integrated with RStudio so that error navigation and PDF/Rnw sync become easy - more comprehensive support to markdown and reStructuredText; markdown is also well supported in RStudio (preview version); see http://yihui.name/en/2012/05/how-to-make-html5-slides-with-knitr/ - other languages like Python and Awk can also be supported, e.g. https://github.com/yihui/knitr/blob/master/inst/examples/knitr-lang.Rmd Suggestions and questions are welcome; please join the mailing list https://groups.google.com/group/knitr or file issues to Github.
