besides I use Lag(x,h) to plot the lagged ts graph, it is very usefful
but when doing the regression(arima, xreg=), i am really not sure if I should use lag(x,-h) or Lag(x,h) from online i see people use lag(x,-h), but i didnt believe that, bc I can't plot the lagged graph using this function. so i think i maybe should use Lag(x,h) as xreg -- View this message in context: http://r.789695.n4.nabble.com/Lag-and-lag-tp4280962p4280973.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
