Here is an example based on the code you gave. My previous post regarding how to include a HTML in a basic Shiny app refers to this additional problem (Bibliography not working when rendering a R Markdown document within an R Shiny App). You basically just need to copy the generated report into another directory. # The `params` object is available in the document. The document will look just as it would otherwise, but it. The rmarkdown package will compile your document into a reactive Shiny app. add Shiny widgets and Shiny render functions to the file’s R code chunks. Rmarkdown::render(tempReport, output_file = file, You can make an R Markdown document interactive in two steps: add runtime: shiny to the document’s YAML header. The script I am sourcing to extract the data includes a parameterised SQL query, which inherits values from the R markdown. The Rmd then sources a series of R scripts to extract and summarise data, create plots etc. Why would I need this Rmarkdown is useful tool for generating data-driven documents in the R environment.

This way the rendered HTML document will include reactive components. Overview The traditional way to add Shiny components to an R Markdown document is through the use of runtime: shiny. Use multiple languages including R, Python, and SQL. Use a productive notebook interface to weave together narrative text and code to produce elegantly formatted output.

It is out of the scope of this book to make a comprehensive introduction to Shiny (. Yesterday I tried to write my first interactive markdown document with R studio and finally it worked ok, but I can not figure out how to access the data inside a render plot().
