acfm | R Documentation |
Produces a grid of plots of the sample ACF (diagonal) and CCF (off-diagonal).
acfm(series, max.lag = NULL, na.action = na.pass, ylim = NULL, acf.highlight = TRUE, ...)
series |
Multiple time series (at least 2 columns of time series) |
max.lag |
Maximum lag. Can be omitted. Defaults to √{n} + 10 unless n < 60. If the series is seasonal, this will be at least 4 seasons by default. |
na.action |
How to handle missing data; default is |
ylim |
Specify limits for the all correlation axes. If NULL (default) the values are a little wider than the min and max of all values. |
acf.highlight |
If TRUE (default), the diagonals (ACFs) are highlighted. |

Additional arguments passed to |
Produces a grid of plots of the sample ACF (diagonal) and CCF (off-diagonal). The plots in the grid are estimates of corr{x(t+LAG), y(t)}. Thus x leads y if LAG is positive and x lags y if LAG is negative.
