[Rd] R packages to send plottable data to external apps

[Mike Marchywka]

I put this up on github in current form where it sort of
works and I can use it for my needs but if anyone 
thinks it fills a niche I guess I could clean it up.

https://github.com/mmarchywka/mjmdatascope

Definitely not ready for users but maybe a deverloper.
In terms of the "Trend" package you mentioned 
maybe one interface would be to emulate that action
too as that was my original interest circa 2007 lol. 

fwiw.
Thanks.

I think r-package-devel is a better place for this. CC'ing there.

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.

Hope it helps,
