Hi,
   
  My query is related to ARIMA function in stats package.
While looking for the time series literature I found following link which 
highlights discrepancy in "arima" function while dealing with 
differenced time series. Is there a substitute function similar to 
"sarima" mentioned in the following website implemened in R? Any pointers would 
be of great help.

  Thanx in advance.
