List and read Excel sheets

Just as readxl and gdata, you can use XLConnect to import data from Excel file into R.

To list the sheets in an Excel file, use getSheets(). To actually import data from a sheet, you can use readWorksheet(). Both functions require an XLConnect workbook object as the first argument.

You'll again be working with urbanpop.xlsx. The my_book object that links to this Excel file has already been created.
