Time Series Analysis with R: Part I

Time Series is a collection of well defined data observations over a period of time.

Examples:

  • Measuring retails sales every month for a year
  • Number of births per month in a City for a specific period
  • Age of death of successive kings of England
  • Production of gold over the years based on US Geological Survey (in Metric Tons)

Analysis of Production of Gold with R:

Please refer to the DataMarket.com for getting the gold related data. It’s free. You can refer to my previous blog to import the data from Excel. In this example I have imported the data using read.csv method using the gdata Library.


 

The above run indicates a start = 1 and End=111 with a frequency of 1.
