The value of the frequency parameter in the ts() function decides the Png ( file = "rainfall.png" ) # Plot a graph of the time series. timeseries ) # Give the chart file a name. timeseries <- ts ( rainfall, start = c ( 2012, 1 ), frequency = 12 ) # Print the timeseries data. Live Demo # Get the data points in form of a R vector.
We create an R time series object for a period of 12 months and plot it. ExampleĬonsider the annual rainfall details at a place starting from January 2012. Start specifies the start time for the first observation in timeĮnd specifies the end time for the last observation in timeįrequency specifies the number of observations per unit time.Įxcept the parameter "data" all other parameters are optional. The basic syntax for ts() function in time series analysis is − <- ts(data, start, end, frequency)įollowing is the description of the parameters used −ĭata is a vector or matrix containing the values used in the time The time series object is created by using the ts() function. It isĪlso a R data object like a vector or data frame. Time series is stored in an R object called time-series object. R language uses manyįunctions to create, manipulate and plot the time series data. Rainfall in a region at different months of the year.
A simple example is the price of a stock in the stock marketĪt different points of time on a given day. Time series is a series of data points in which each data point is associated R - Time Series Analysis R - Time Series Analysis
