   You can checkout the images/ directory. let's take ruby for example.

   images/ruby
   ├── Dockerfile
   ├── app.rb
   └── fx.rb
   

   you should prepare a Dockerfile and an entry programe (app.rb), then call a a simple function defined in fx.rb.

   then if everything works well when you do docker run to test your function, you can make PR, I will include your change into fx.

   @flaviobarros I initialize it, but with some small issue, I will fix it soon. https://github.com/metrue/fx/tree/support-R/images/R

   basically, it has some issues in package installation of R's install_packages('jug')

   I am trying to support R, but I could make it work since dependencies issue.
   could you help check it when you have time and it happens you're a R programer.

   basically, the problem is the i still could not find the library event they are installed.

   Sorry for the delay. I guess the simplest solution would be a go server and an R app taking input from stdin and outputing to stdout

   Yeah, I want to do in that way for other languages support at first, but when we do that it's not possible to deploy some function that has dependencies ( I mean when a function will require third party library installed first ) , but if we do it in independent Docker container, we have possibilities.

   I would also suggest to start a container passing stdin and then get the stdout+stderr when it closes (or is closed from fx by a timeout).

   This would make callable functions any container handling I/O exchange
