WebR: R compiled for WebAssembly and running in the browser
summary
WebR brings a full R environment into the browser by compiling R to WebAssembly so all computation runs client-side and no local or cloud R servers are needed. The build uses Emscripten with LLVM/GCC workarounds to compile R’s Fortran-heavy code; the result is a sizable Wasm bundle (tens of megabytes) that executes R, installs packages and renders plots. Demonstrated specifics: R compiled to WebAssembly, Emscripten toolchain, tidyverse/ggplot.
