Execute R Script ARIMA Process Fails

Hi,
I'm trying to use R to build ARIMA model forecast with it. The script works well in R software, but when I try to use in Rapidminer with Execute R I always get an error message (bellow the detailed message).

I try to adapt an example process with R script to train and forecast with ARIMA, I found in Rapidminer.
Both, my script and the example, return the same error message.

Note: With other processes that use Execute R, like the tutorials, seems that there is no issue. 

Enclosed the process.

Thanks for your help,
Pedro
