arima

Hola!

I got problems using an objects returned from arima
(in KalmanSmooth(my.ts, ModArima$model), because
my.ts showed up to have storage mode "integer" (is.integer(my.ts was
TRUE). 

Should storage.mode() of a ts be allowed to be integer, 
should ts() someplace say storage.mode(ts.out) <- "double", or
maybe inside arima()
storage.mode(x) <- "double"
storage.mode(xreg) <- "double"
?
