r - What is a neat command line equivalent to RStudio's Knit HTML?

Question

What is a neat command line equivalent to RStudio's Knit HTML? Given an .Rmd file, you can use RStudio to knit .html, .docx and .pdf files using Knitr. It would be great to shift this process completely to the command line. My approach so far:

Rscript -e "library(knitr); knit('test.Rmd')"  # This creates test.md
pandoc test.md >> test.html

This works fine, but the resulting test.html does not come with the same pretty make over as in RStudio. Any suggestions how one should best knit .Rmd files to .html via the command line, and end up with a pretty .html?

Extra question: What would be the best command line solution for .pdf or .docx?

Answer 1

rmarkdown::render("test.Rmd", "html_document")
