Handling error messages and warning in

Objective: To capture the warning thrown by the R script in R.NET

When I use the below script in R Console it gave me the output as  string "Warning"
jj = ts(scan("jj.dat"),  start=1960, frequency=4) 
tryCatch(arima(jj, order = c(1, 0,1)), warning=function(w) cat("Warning"))

I tried to use the same code in R.NET and expected to get the stirng "Warning", but I'm getting Parser Exception showing "Code error". Below is the code snippet which I tried in R.NET.


                string script = "tryCatch(arima(jj, order = c(4, 0,6)), warning=function(w) cat(\"Warning\"))";
                string str=engine.EagerEvaluate("script").AsCharacter().First();//*

catch (Exception ex)
                string s =ex.ToString();

Kindly help me on this trouble.
