Arduino and R interface

Using Arduino Interfacing w/ Software on the Computer
1

Can someone point me to a reference for an interface between Arduino and R? I have seen some approaches using Processing, or Firmata, but nothing seems clear to me.

I have read analog data through an Arduino script, where it is converted to digital values and scaled, but I need to expose it to the R environment. This is not an extreme sampling problem. It is joystick data that I want to indicate a change of direction. I also need to write text data at times from R onto an LCD that I have successfully configured with my Arduino.

Arduino Uno, MacOS 10.8.5, R 3.2.1

And yes, this is fairly urgent, for a demonstration this weekend.

Thanks

What is R?

Sorry. The R Statistical Programming Language. It is an open source, interpreted language, but with many low level functions that are reasonably fast. There are a large number of user-contributed packages, but I haven't seen anything that deals with this much.

If there are functions to open, read and write a serial port (what Windows refers to as COM ports) you should be able to communicate with an Arduino.

The concept in the Python - Arduino demo should apply in other languages.
