webR 0.2 Overview: R in the browser | George Stagg | Posit

WebR is a version of the statistical language R compiled for the browser and Node.js using WebAssembly, via Emscripten.
WebR makes it possible to run R code in the browser without the need for an R server to execute the code: the R interpreter runs directly on the user’s machine. Several R packages have also been ported for use with webR, and can be loaded in the usual way using the library() function.

This so awesome!!! You could write code directly from tablet or Phone. I'm a useR 4ever and the fact you guys still working to make it greater Just make me being better at R

[@mikegaunt837]

Do you have any idea how the community is using WebR right now? I make reports for corporate clients and see WebR as a tool to SLIGHTLY Shiny-ify items that could be enhanced beyond the limitations of an HTML widget (crosstalk + leaflet + plotly + etc). So less focused on teaching and running things in the browser.

Great progress, keep it up

[@jonathanwking]

This is just amazing. Beyond this being a usable R, my guess is that if you can do R in wasm in not sure there’s anything you can’t do?

nice job albeit not in dark mode ! is this purported to be the equivalent of a Jupyter notebook template ?

[@hubstrangers3450]

Thank you....would like to know how did it turn from a single threaded scenario to a multi thread, what's the underlying mechanism.....thank you

[@georgestagg]

The multithreading mechanism is provided by JavaScript Web Workers.

Thank you....

George - My University is interested in loading this on one of our servers for our students to use from one of our testing centers. We are having some installation issues. Where is the best source to obtain the latest installation?

[@PositPBC]

The best place to get help like this is to reach out on the issues page of the webR repo.

[@angadanalytics2896]

Wow..... but one question , do we need to make user account for this ?

[@georgestagg]

Nope, it's free and open source! You can experiment with webR simply by visiting the demo website.
