Can anyone tell me what's going on here? x <- matrix(data=c(1,2,3,4,5),ncol=1) x1 <- lag(x,k=1) x x1 x - x1
That's with x specified as a column vector, but the same thing happens when it's a row vector. x <- c(1,2,3,4,5) x1 <- lag(x,k=1) x x1 x - x1 When the documentation says "Vector or matrix arguments x are coerced to time series." What does that mean?
