R help - Feb 2017 - JRI: obtain error messages from the R engine

Dear all,

I am using JRI to execute a number of computations using the R engine. As
pointed in various tutorials out there in the web I am using the eval method of
the Rengine class, e.g.:

engine.eval("meanVal=mean(rVector)");

At some point the eval method starts returning NULL, which according to the
documentation means "something went wrong". However, I can not
identify in the Rengine class a property or a method that would provide an error
message, error status or R console output to identify the cause. Is there any
way to obtain detailed information on what might be happening?



Thank you.
