I'd like to access data in my R session from elsewhere via HTTP. My particular use case would be R on Linux, accessing data from Windows, all on the same intranet.
Naively, when I say this, I imagine something like: > theData <- big.calculation.returning.data.frame() > startHttpServer(port=8675) (blocks until I C-c it) Elsewhere... http://linuxmachine:8675/htmlDF?theData -> HTML table version of data frame or http://linuxmachine:8675/csvDF?theData -> CSV export of data frame Then I C-c my server and continue working in R. Rserve has its own protocol, plus it spawns extra processes. biocep looks interesting, but it's far more ambitious than this, and I can't tell if it would actually work in this case. svSocket looks interesting, but (if I understand it correctly) it would be a lot of work to implement HTTP over its raw sockets. Basically, I have a few tools (including Excel) that know how to get data from web services, but no way to export data from R in a way that they can see. I'm spoiled a little by having used q (from kx.com), which embeds a HTTP server in the interpreter and makes this kind of access very easy; I'd like to have the same thing in R.
