We will start with looking at some already existing time series datasets. We will move on to creating or defining our own time series on the basis of some hypothetical case. We will see how to work with time series. We will also use some packages specifically created for handling time series.
There are many datasets available with R that are of the time series types. Using the command class, one can know if the dataset is time series or not. We will look into the AirPassengers
dataset that shows monthly air passengers in thousands from 1949 to 1960. We will also create new time series to represent the data.
Perform the following commands in RStudio or R Console:
> class(AirPassengers) Output: [1] "ts" > start(AirPassengers) Output: [1] 1949 1 > end(AirPassengers) Output: [1] 1960 12 > summary(AirPassengers) Output: Min. 1st Qu. Median Mean 3rd Qu. Max. 104.0 180.0 265.5 280.3 360.5 622.0
