I'm writing a C++ application using R-embedding to do some forecast process. I also use R_tryEval instead of R_Eval to run my R-script, so that in case of error I know exactly in which line number was the last error. In particular, from time in time y get some error messages refering an exceptional condition in the arima model. I want to catch these error messages from de C code (or at least the code error number) to take some corrective actions. Is there any way to do that ? Regards, Jorge W. Cardoso
