corgram: Calculate and Plot a Correlogram

Description

corgram calculates the values of a correlogram (autocorrelation function or ACF) and plots it.

Usage

corgram(y, wt = 1, maxlag = NULL, partial = FALSE, add = FALSE,
  lty = 1, xlim = NULL, ylim = NULL, xlab = NULL, ylab = NULL,
  main = NULL, ...)

Arguments

y

A time series vector.

wt

Indicator vector with zeros for values to be ignored.

maxlag

Maximum number of lags for which the correlation is to be calculated.

partial

If TRUE, the partial autocorrelation function (PACF) is plotted.

add

If TRUE, adds a new correlogram to an existing plot.

Value

corgram returns a two-column matrix containing the (partial) correlogram coordinates.

Examples

y <- rnorm(100)
corgram(y)
corgram(y, partial=TRUE)
# }
