  3. Introduction to Importing Data in R

Exercise

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 (view). The my_book object that links to this Excel file has already been created.

Instructions

100 XP
  • Print out the sheets of the Excel file that my_book links to.
  • Import the second sheet in my_book as a data frame. Print it out.
