[R] incremental learning for LOESS time series model

Hi All, I am currently working on some time series data, I know I can use LOESS/ARIMA model. The data is written to a vector whose length is 1000, which is a queue, updating every 15 minutes, Thus the old data will pop out while the new data push in the vector. I can rerun the whol
