I got the error below using the code in the blog post.

The code below, however, creates date object by leveraging zoo package.

d1 <- data.frame(c(10^as.numeric(fitted(arima)), # fitted and predicted
                   10^as.numeric(predict(arima, n.ahead = 12)$pred)),
                 as.numeric(AirPassengers), #actual values
                 as.Date(as.yearmon(time(AirPassengers)))
