Combining R and Python with GraalVM
GraalVM is a multi-language runtime that allows to run and combine multiple programming languages in one process and operating on the same data without the need to copy the data when crossing language boundaries. Moreover, the dynamic just-in-time compiler included in GraalVM is capable of applying optimizations across the languages boundaries. The languages implemented on top of GraalVM include FastR, an alternative R implementation, C, Ruby, JavaScript, and recently added GraalPython.The talk will present interesting ways how R and Python can be combined into a polyglot application running on GraalVM, for example using R package from Python or vice versa, and briefly explain how this interoperability works on the technical level. One of the most important parts of a language ecosystem is tooling and especially interactive debugger. The talk will also present how one can debug multiple GraalVM languages at the same time in the Google Chrome Dev Tools, for instance stepping from R into C code.
