Thanks. I take it though you see "R" in this role as adding to the capabilities of
the viewers, maybe adding some quick model fits over FEM results or something?
Right now I was imagining working with freefem and rolling my own c++ code
with supporting use of R code. Ideally I could easily overlay stuff without
messing around with temp files. There are a lot of R things, probably
optimizations etc, that may be nice to view as they progress
with more than just a figure of merit.
Right now I'm just trying to use Runge-Kutta on a simple orbit
and the mjmdatascope output is much more useful on-the-fly
than text or after the fact.

At ORNL, we worked with VisIt (a sibling of Paraview, both funded largely by DOE) around 2016 and made an in situ demo with R. We used packages pbdMPI (on CRAN) and pbdDMAT (on GitHub/RbigData), which were in part built for this purpose. Later also the package hola (on GitHub/RbigData) was built to connect with adios2, which can do buffered in situ connections with various codes.
But the VisIt developers were not interested in R (preferring to roll their own), so that direction fizzled. Paraview is a competetive sibling of VisIt, so I don’t know if they would be interested. The packages we developed are viable for that purpose. There is a lot in R that could benefit Paraview (or VisIt).
