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. When using the readWorksheet() function, the sheet argument can accept either the name of the sheet (as a string) or the sheet's position number (as an integer) within the workbook.
You'll again be working with urbanpop.xlsx (view). The my_book object that links to this Excel file has already been created.
