R in JavaScript

rjs: R in JavaScript

Introducing R in JavaScript, a way to insert R code directly into websites, powered by OpenCPU.

You can use it in 3 easy steps.

Step 1

Add <script src='https://cdn.jsdelivr.net/gh/kdpsingh/rjs@master/r.js'></script> anywhere in your html file (or download r.js locally).

Step 2

Add class = "r-code" to any html element containing R or Rmd code.

That's it.

After rjs runs, the class will be changed to "r-code-output". You can run R code dynamically in JavaScript by setting the class of any HTML element to "r-code" and then calling rjs();.

Step 3 (optional)

Want to bring your R workspace with you? No problem. Add file = "filename.RData" to the same HTML element containing class = "r-code", and rjs will automatically load the .RData file before running your code.

A single .RData file can contain multiple R objects, so be sure to save all the objects you will need in a single .RData file. Make sure you don't include any sensitive information in the .RData file because it will be uploaded to a public server.

rjs can:

• Auto-detect and process both R and Rmd formats
• Handle special characters in the input
• Render to non-html formats such as pdf_document (rjs automatically provides a link to the file)
• Load a local R workspace file (an .RData file)
