So I have finally switched to knitr for doing my vignettes. The result is satisfactory, but the process was not entirely painless. The command to run instead of “R CMD Sweave foo.Rnw” is Rscript -e 'rmarkdown::render("foo.rmd")' I think that the concept of writing a package which has the main purpose to generate documentation in literate
