Lag a Time Series

Compute a lagged version of a time series, shifting the time base back by a given number of observations.

lag(x, ...)

## Default S3 method:
lag(x, k = 1, ...)

`x`	A vector or matrix or univariate or multivariate time series
`k`	The number of lags (in units of observations).
`...`	further arguments to be passed to or from methods.

Vector or matrix arguments x are coerced to time series.

lag is a generic function; this page documents its default method.

A time series object.

Note the sign of k: a series lagged by a positive k starts earlier.
