    The general solution (works regardless of the R version):

    Rscript -e "library(knitr); knit('myfile.Rmd')"

    Since R 3.1.0, R CMD Sweave has started to support non-Sweave documents (although the command name sounds a little odd), and the only thing you need to do is to specify a vignette engine in your document, e.g.

    %\VignetteEngine{knitr::knitr}

    To see the possible vignette engines in knitr, use

    library(knitr)
library(tools)
names(vignetteEngine(package = 'knitr'))
# "knitr::rmarkdown" "knitr::knitr" "knitr::docco_classic" "knitr::docco_linear"
