ACF Plot with ggplot2: Setting width of geom_bar

Question

With acf we can make ACF plot in base R graph.

x <- lh
acf(x)

Answer 1

From the forecast package comes a function ggtsdisplay that plots both ACF and PACF with ggplot. x is the residuals from the model fit (fit$residuals).

forecast::ggtsdisplay(x,lag.max=30)

Answer 2

@konrad; try the following code:

library(ggfortify)
p1 <- autoplot(acf(AirPassengers, plot = FALSE), conf.int.fill = '#0000FF', conf.int.value = 0.8, conf.int.type = 'ma') 
print(p1) 
library(cowplot) 
ggdraw(switch_axis_position(p1, axis = 'xy', keep = 'xy'))

Answer 3

You're probably better off plotting with line segments via geom_segment()

library(ggplot2)

set.seed(123)
x <- arima.sim(n = 200, model = list(ar = 0.6))

bacf <- acf(x, plot = FALSE)
bacfdf <- with(bacf, data.frame(lag, acf))

q <- ggplot(data = bacfdf, mapping = aes(x = lag, y = acf)) +
       geom_hline(aes(yintercept = 0)) +
       geom_segment(mapping = aes(xend = lag, yend = 0))
q

Answer 4

How about using geom_errorbar with width=0?

ggplot(data=bacfdf, aes(x=lag, y=acf)) + 
    geom_errorbar(aes(x=lag, ymax=acf, ymin=0), width=0)
