...time series of length about 200000 elements. I would like to have a lag 1 of this time series. I did the following: logprice = log(price, base=exp(1)) # this is my log price which is a vector of price time series of length 200000 ts_logprice = as.ts(logprice, frequency=1) # convert to time series lag_logprice = lag(ts_logprice, 1) # get the lag When I do: ts_logprice[1:10] == lag_logprice[1:10] The result returns TRUE for the first 10 elements which I do not expect that.
