PERFECT FOR

Learning R on the go. Quick data analysis. Statistical calculations. Code prototyping. Teaching and demonstrations.

Built with webR, an open-source MIT-licensed project that compiles R to WebAssembly. Learn more at https://r-wasm.org. This app is not affiliated with the webR development team or Posit.

Note: First launch requires a few seconds to initialize the R environment. Some computationally intensive operations may be slower than desktop R due to WebAssembly constraints. This environment is not able to support developing an R package or writing compiled code.
