Convert an Sweave document to work in knitr
Sweave2knitr is a simple Python script that helps to convert Sweave LaTeX documents to be instead compatible with Yihui Xie’s knitr package. It is based on and inspired by Jeromy Anglim’s blog entry, “Converting Sweave LaTeX to knitr LaTeX: A case study.”
Warning: This conversion is not an exact science. While this catches some of the most common issues faced when converting from Sweave to LaTeX, there are a virtually infinite number of special cases that will have to be handled. Furthermore, this is a very early version that has been tested on only a few documents. Try it on your own Sweave documents: contributions are strongly encouraged!
If infile.Rnw is your Sweave LaTeX file, use
Sweave2knitr infile.Rnw outfile.nw
You can then use
Rscript -e “library(knitr); knit(‘outfile.nw’, ‘outfile.tex’)” pdflatex outfile.tex
To create the .tex file and turn it into a PDF.
