Try this. It uses Matthias' trick for getting rid of lag 1. The it defines a new local plot.acf and then defines a new local plot.acf which
# test data set.seed(1) x <- rnorm(1000) # run acf x.acf <- acf(x) # remove lag 0 -- see Matthias' post x.acf$acf[1] <- NA # plot with custom x axis plot(x.acf, xaxt = "n") axis(1, seq(12, length(x.acf$acf), 12)) On 8/18/06, Stefano Sofia <[EMAIL PROTECTED]> wrote: > I need to modify the graph of the autocorrelation.
