You can also see it in action in jri (in the Rengine.c file).

I don't think it is documented as it is not part of the API -- see for
example R's src/main/context.c where you find
R_tryEval is in Rinternals.h (so public), but not in the API.
That doesn't stop several projects from using it but we know it can break.
