plot.acf {ts} | R Documentation |
Plotting method for objects of class "acf"
.
plot(x, ci = 0.95, type = "h", xlab = "Lag", ylab = NULL, ylim = NULL, main = NULL, ci.col="blue", ci.type=c("white", "ma"), ...)
x |
an object of class "acf" . |
ci |
coverage probability for confidence interval. Plotting of
the confidence interval is suppressed if ci is zero or
negative. |
type |
the type of plot to be drawn, default to histogram like vertical lines. |
xlab |
the x label of the plot. |
ylab |
the y label of the plot. |
ylim |
numeric of length 2 giving the y limits for the plot. |
main |
overall title for the plot. |
ci.col |
colour to plot the confidence interval lines. |
ci.type |
should the confidence limits assume a white noise input or for lag k an MA(k-1) input? |
... |
graphics parameters to be passed to the plotting routines. |
The confidence interval plotted in plot.acf
is based on an
uncorrelated series and should be treated with appropriate
caution. Using ci.type = "ma"
may be less potentially
misleading.
