[[!meta title="Introducing Sweavealike"]] I use [R](http://www.r-project.org) a lot. It's one of the primary tools I use in my day job as a scientist analyzing large datasets. If you use [LaTeX](http://ctan.org) with R (as I often do), you probably use Sweave to interleave R output and figures with your text describing those figures using the noweb method of literate programming. [Sweavealike](http://git.donarmstrong.com/?p=ikiwiki_plugins.git;a=blob;f=sweavealike.pm;hb=HEAD) is a plugin for [IkiWiki](http://ikiwiki.info) that tries to do some of the useful things for IkiWiki that sweave does for R and LaTeX. You use it like the following: \[[!sweavealike echo=1 code=""" a <- 1 a <- a + 10 print(a) """]] which produces this result when run: [[!sweavealike echo=1 code=""" a <- 1 a <- a + 10 print(a) """]] You can also generate figures with it: \[[!sweavealike fig=1 echo=1 results="hide" code=""" plot(1:10,(1:10)^2,xlab="x",ylab=expression(x^2),main="Example Figure") """]] [[!sweavealike fig=1 echo=1 results="hide" code=""" plot(1:10,(1:10)^2,xlab="x",ylab=expression(x^2),main="Example Figure") """]] The plugin itself uses the neat Statistics::R perl module to handle all of the heavy lifting. I personally plan on using this plugin to help write some more entries in my learning R series of posts that I'm beginning to work on. Hopefully I'll find and fix most of the bugs as I embark on that process so anyone else who uses the plugin won't, but feel free to e-mail me if something isn't working as it should. Finally, you shouldn't run this plugin on a publicly editable IkiWiki instance, because that would be a trivial local user exploit as R can run arbitrary code, read and write to arbitrary files, exhaust all memory, etc. [[!tag ikiwiki debian tech r]]
