How to make the output recognizable in Sweave

I am using Sweave to be able to combine LaTeX and R. I find useful to be able to remove the prefix ">" and "+" from the input writing options(prompt=" ", continue=" ") .

I would like to find a way to make the output recognizable from the input, for instance adding a prefix "#" to the output (as it happens with R Markdown).

Any help?

Solution

  • I'm not sure if you know that knitr can also compile .Rnw documents (Sweave), in addition to .Rmd (R Markdown). You just pass the file path to knitr::knit(), e.g.,

    knitr::knit('test.Rnw')

    And you will get the .tex output file. If you want to get the PDF output directly, you may call:

    knitr::knit2pdf('test.Rnw')

    By default, knitr doesn't add the prompt character > or + to your code in the output.
