[Wikipedia](https://en.wikipedia.org/wiki/R_(programming_language)#cite_note-12) states R to be partially written in R, and other parts in C and Fortran. Recently, @KjellJorner initiated a discussion how to engage [Fortran from Python](https://fortran-lang.discourse.group/t/interfacing-fortran-code-from-python/1280) with examples _like_ `f2py`. Perhaps in contrast to you @Beliavsky, or others, I do not possess any working knowledge about R and still ask – out of curiosity\*: is there a similar bridge, while working within R, to reach out for Fortran? For me, [FortranCallsR](https://github.com/cran/FortranCallsR) found on the same [index](https://github.com/cran?q=fortran&type=&language=&sort=) mentioned by you looks just the other way around … \*) In part equally a speculation: [fortran-lang.org](http://fortran-lang.org) might benefit from a directory-like compilation in tune of «if you happen to work in language `example`, you may reach (back) to Fortran e.g., with module / library `f2example` with typical limitations of x and y». This guide need not to be exhaustive. --- _[View the full topic](https://fortran-lang.discourse.group/t/r-packages-with-fortran-code/1391)._
