Connect to a workbook
When working with XLConnect, the first step will be to load a workbook in your R session with loadWorkbook(); this function will build a "bridge" between your Excel file and your R session.
In this and the following exercises, you will continue to work with urbanpop.xlsx, containing urban population data throughout time. The Excel file is available in your current working directory.
