R packages to send plottable data to external apps
I think r-package-devel is a better place for this. CC'ing there.

I was curious what R packages, or indeed any other applications, exist to plot streamed data from arbitrary data generators. It need not be publication quality plotting but it should be easy to use like an oscilloscope.
The last time I checked, there wasn't any R package suitable for plotting high-throughput streaming data. There's a nice command-line utility called trend [1] that I extensively used in the past as an oscilloscope to visualize the output from a DAQ card. I don't see any new development there, but it does exactly what it promises; it's easy to use, quite configurable and very fast. Old but gold. I also explored VisPy, which is much more ambitious, but at that time the API had a limitation that didn't allow me to achieve what I required, and I haven't looked at it ever since, but the project seems in good shape.

I was working on something called datascope that I am using for 1D finite difference monitoring and recently interfaced it to freefem. I also created an R package. If there is any interest in something like this I guess I could put it up somewhere when it is more usable or if you can suggest some similar popular packages that would be good too. Is there something I could drop-in to the attached code and get something like the attached output that could also be switched to other data sources? This right now works via linux fifo and somewhat by UDP. It can queue data and stop making it if no one seems to be consuming it depending on the channel. Thanks.
