runr
This is an R package providing mechanisms to run with external programs such as Julia, Shell, and Python, etc. The basic idea is to open a background process, pipe the source code into the process, evaluate it, and obtain the printed results.
At the moment, there are only a few very simple engines:
- a Julia engine (using TCP sockets; an example)
- a
bashengine (using TCP sockets; an example) - a
pythonengine(using TCP sockets; an example) - a
rubyengine(using TCP socketss; an example)
Contributions welcome!
This package was originally designed for the language engines in knitr, but it might be useful for more general cases.
