R Dataset / Package datasets / AirPassengers

On this R-data statistics page, you will find information about the AirPassengers data set which pertains to Monthly Airline Passenger Numbers 1949-1960. The AirPassengers data set is found in the datasets R package. You can load the AirPassengers data set in R by issuing the following command at the console data("AirPassengers"). This will load the data into a variable called AirPassengers. If R says the AirPassengers data set is not found, you can try installing the package by issuing this command install.packages("datasets") and then attempt to reload the data with the library() command. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the AirPassengers R data set. The size of this file is about 2,567 bytes.

Examples

## Not run: 
## These are quite slow and so not run by example(AirPassengers)## The classic 'airline model', by full ML

seasonal = list(order = c(0, 1, 1), period = 12)))
update(fit, method = "CSS")
update(fit, x = window(log10(AirPassengers), start = 1954))
pred <- predict(fit, n.ahead = 24)
tl <- pred$pred - 1.96 * pred$se
tu <- pred$pred + 1.96 * pred$se
