We will use the script from the analythium/rmarkdown-docker-examples GitHub repository. In this post, we review how to dockerize R Markdown documents with different runtime environments. This way the rendered HTML document will include reactive components. Now you can add Shiny widgets and Shiny render functions to the file’s R code chunks. If you just need a nice format for presentation offline, then RMarkdown can produce some very nice looking formats.įlexdashboard is a bit of both - it is essentially an RMarkdown document that allows Shiny elements to be placed within it.Īll the above is further complicated by HTML Widgets - these render in JavaScript that can do a lot of interactivity by itself, so if you can find a JavaScript library that gives you say dropdowns, then you can use that in RMarkdown instead of using Shiny, without hosting a Shiny server. Because interactive R Markdown documents differ from Shiny apps in subtle ways, serving them is also slightly different. I am wondering if it is possible to pass a plot object to Rmarkdown document when generating a downloadable report using shiny For instance,I have a P2 plotly object, I want to pass it to Rmarkdown document. Runtime: Shiny The way to make R Markdown document interactive/reactive is to add runtime: shiny to the document’s YAML header. For a full solution where data is updated and processed in real-time, Shiny is your best option. It generally comes down to the amount of interactivity you need in your app. Only a normal HTML server if you want to host those (e.g. Github Pages lets you host for free) Nameįree for Shiny Server, $9995 for Shiny Server Pro, $9+ a month Shinyapps.io library(shiny)įile.copy(file, paste("reportDir/", Sys.time(), ".There are a few options for data presentation using R so an overview is first presented to help you decide which to choose. Shiny widgets can also be invoked directly from the console (useful during authoring) and show their output within the RStudio Viewer pane or an external web browser. Here is an example based on the code you gave. Shiny widgets enable you to create re-usable Shiny components that are included within an R Markdown document using a single function call. You basically just need to copy the generated report into another directory. You can turn any HTML-oriented R Markdown documents to Shiny documents by adding runtime: shiny to the YAML metadata as a top-level field, e.g. # The `params` object is available in the document. Rmarkdown::render(tempReport, output_file = file, Here is the runtime-shiny/index.Rmd file as our first document (following. # child of the global environment (this isolates the code in the document The way to make R Markdown document interactive/reactive is to add runtime: shiny to the document’s YAML header. # Knit the document, passing in the `params` list, and eval it in a Rendering of the user interface and data and Serving of the document to end users. # Set up parameters to pass to Rmd document The execution of documents with runtime: shinyprerendered is divided into two main contexts. To change the shiny. TempReport <- file.path(tempdir(), "report.Rmd")įile.copy("report.Rmd", tempReport, overwrite = TRUE) You an also pass arbitrary paramters to runApp, so this should work too: rmarkdown::run ('myfile.Rmd', shinyargslist (host'0.0.0.0')) Neither of these will work with the Run Document button that button starts a new R session in which to render the document. # case we don't have write permissions to the current working dir (which 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. # Copy the report file to a temporary directory before processing it, in You can make an R Markdown document interactive in two steps: add runtime: shiny to the document’s YAML header. FYI.the rest of the original code is the same, except a new variable. This enables some basic styling inside the creation of textoutput, such as bold text, line breaks and a href external links. # For PDF output, change this to "report.pdf" The solution Ive found is to create a list with a for loop, then unlist this before passing the result (s) to the HTML output handled by renderUI. SliderInput("slider", "Slider", 1, 100, 50),ĭownloadButton("report", "Generate report") Ideally, I'd like to do this from within the downloadHandler call so that I do not have to generate the report twice.Ī minimal example (adapted from this shiny article): library(shiny) I would like a copy of the report to be saved on the shiny host each time a user uploads data to generate a report. I have a shiny app that generates a downloadable report using rmarkdown, which works fine.
