Is it possible to automate R markdown files?

Question

I need to generate a thousand R Markdown files, each essentially the same, just with different titles and a different subset of the data. Is there a way to store those titles and subsets in objects and automate creating and knitting the R Markdown files?

Answer 1

Yes. When you klick the knit button in Rstudio, it calls the function rmarkdown::render() . This can also be done in code, either in a for loop, with apply or the purrr -version of apply called map . You will need to create a rmarkdown-document that takes parameters for the title and the subset first and then pass these to the render-function in said way.

For an introduction to paramters in your documents have a look at the documentation here .
