        6.8.2 accessing List elements

        Let’s now understand how to access  list elements in R programming. You will be using the list that you created in the
        previous section.
        Example

        Enter the following code snippet:

             #In order to give names to the elements of the list:
             names(data_list) <- c("Month", "Matrix", "Misc")

             #Access the first element of the list.
             print(data_list[1])     #Accessing the First element
             #Access the third element.
             print(data_list[3])     #Accessing the Third element
        By using the name of the element access the list elements.

        Enter the following code snippet:

             print(data_list$Matrix)  #Using name of access element
             names(data_list) <- c("Month", "Matrix", "Misc")
             names(data_list) <- c("Month", "Matrix", "Misc")

             print(data_list[1])     #Accessing the First element
             print(data_list[3])     #Accessing the Third element
             print(data_list$Matrix)  #Using name of access element
             names(data_list) <- c("Month", "Matrix", "Misc")
