-----------------------------------------------

I think this would be very useful to have if we can get it in before the 2.0 time frame.

> When you have an error in your R code using the RDD API, you always get as error message:
>     Error in if (returnStatus != 0) { : argument is of length zero
> This is not very useful and I think it might be better to catch the R exception and show it instead.
