Session Summary:

In this talk I introduce webR, a port of R to WebAssembly using Emscripten. WebR brings a full R environment to the browser, enabling R code execution, numerical analysis, loading packages and more. No local or cloud-based R servers are required as all computation is performed within the browser. I give a brief overview of our build process for webR, describing the toolchain and some of the issues we encountered. A publicly available web-based R session is demonstrated, with package and plotting support.
