Since I am becoming a Java programmer, and an R evangelist, I found very interesting the FastR project whose scope is to provide a Java implementation of the R language. This would be really interesting, especially thinking to a possible integration among OMS and R, which would be very helpful for data management and I/O for model components.
Jan Vitek, one of the authors of the code, gave a nice presentation about, that can be found below the image.
Any comment is left to the readings and to the trial of the software. Eventually, other material and code itself, can be found at github
