Exercise

Add worksheet

Where readxl and gdata were only able to import Excel data, XLConnect's approach of providing an actual interface to an Excel file makes it able to edit your Excel files from inside R. In this exercise, you'll create a new sheet. In the next exercise, you'll populate the sheet with data, and save the results in a new Excel file.

You'll continue to work with urbanpop.xlsx. The my_book object that links to this Excel file is already available.
