Interesting to see this come up, as I only recent came across Pure Data [1]. I find it surprising that the numerical programming languages aren't flow-based.

Interesting to see this come up, as I only recent came across Pure Data [1]. I find it surprising that the numerical programming languages aren't flow-based. R makes good use of pipes, and I guess it works a bit like flow-based programming, except that they are all are 1D segments of variable length, and no branches. Sometimes I think that Go's channels are bit a flow-like (though it is otherwise very much not functional!). If anyone knows of a flow-based programming add-on to R, I'd be very curious.
