As a newbie to R I have the following question. I would like to compare values
in a time series with values of the same series x observations ago. In gretl
this is simply done like so:
In R, I seem not to get it working. I have tried lag(data,-x) to obtain the
lagged time series which produces the following error message:
Error in attr(x, "tsp") <- c(1, NROW(x), 1) :
invalid time series parameters specified
Can anyone enlighten me on how to accomplish this task in R?
Thanks.
