[Rd] Background session with R

[Stravs, Michael]

Hi,

I am working on some code to have a background R process running that I can submit data to, check computation progress, and retrieve results later. I am aware that "parallel" does a lot of that - however, "parallel" shuts down the nodes when I quit the master process. On the contrary, I would want these nodes to continue running, so I can fire up R again later and reconnect to the nodes to retrieve the results.

The use case is Shiny apps, where I want a thin frontend as a GUI, workflow launcher and result viewer, and launch background computation that isn't dependent on the Shiny script staying alive.

Has this been done already, and/or are there simple modifications of parallel/snow/etc that allow this? My current WIP thing uses Rserve.

(shiny-discuss cc'd).
