Exercise

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 (view), containing urban population data throughout time. The Excel file is available in your current working directory.

  • Use loadWorkbook() to build a connection to the "urbanpop.xlsx" file in R. Call the workbook my_book.
