Hello all,

I am using RInside in my application to execute some R code with parseEval() 
and parseEvalQ().

However, if the R code passed to parseEval() contains syntax errors, my 
application crashes with an error ("Error: Parse Error: <expression>. 
Execution halted").

I tried putting the parseEval() call inside a try...catch block (as per the 
RInside examples) but no exception seems to be thrown.

Isn't there any way to detect these parse errors without crashing the
