    Creating a time series
    The ts() function will convert a numeric vector into an R time series object.
    The format is ts(vector, start=, end=, frequency=) where start and end are the times of the first and last observation and frequency is the number of observations per unit time (1=annual, 4=quartly, 12=monthly, etc.)..

  • ARIMA is a popular statistical method used to analyze time series data because it can capture the complex interactions between past and present observations in the data.
    ARIMA models assume that the data is stationary, meaning that the mean and variance of the data do not change over time.
  • plot() function - basic parameters
    xts() function is the most useful tool in the R time series data visualization artillery.
    It is fairly similar to general plotting, but its x-axis contains a time scale.
    You can use plot() instead of plot. xts() if the object used in the function is an xts object.
In this section, we consider graphical and numerical descriptive statistics for summarizing the linear time dependence in a time series. 5.2.1 Sample 
j j , and gives a graphical view of the linear time dependencies in the observed data. Example 5.17 (SACF for the Microsoft and S&P 500 returns). The R function 

How to analyse time series data in R?

The first thing that you will want to do to analyse your time series data will be to read it into R, and to plot the time series

You can read data into R using the scan () function, which assumes that your data for successive time points is in a simple text file with one column
