Procedure 2: Establish Range in R

To establish the range of the Interim_Close in the AAPL data frame use the min() function typing:

min(AAPL$Interim_Close)

Run the line of script to console:

It can be seen that the smallest value in the Interim_Close vector of the AAPL data frame is 50.67, to retrieve the largest value use the max() function by typing:

range(AAPL$Interim_Close)

Run the line of script to console:

To establish the range value subtract the largest value from the smallest value which can be achieved by using the diff() function on the vector returned from the range() function as:

diff(range(AAPL$Interval_Close))

Run the line of script to console:

It can be seen that the range has been returned as being 651.43.
