[R-pkg-devel] [Rd] R packages to send plottable data to external apps

[Iñaki Ucar]

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,
