Of course, the data sets you can utilize by manually entering data will be relatively small and tedious to deal with. The open source statistical software R however has a number of built in data sets with many of them including a relatively large number of values. We will be utilizing some of those data sets throughout the remainder of this text. To see what data sets are actually available, execute the command data(). You can load the data from one of these sets by executing the data command with the desired data set name inside the parenthesis and then print out the first few data values with headers using the head command. Execute the interactive cell below and play around with some of the data sets. Remove the hash tag symbol to ’uncomment’ those lines as needed.
