Lesson 7: The Data Frame

Overview Section

Now that we are working with more than on variable, we need to consider how data sets are stored in R, which brings us to the "dataframe", the R equivalent of a spreadsheet. We'll be following Chapter 7 in Essential R.


Upon completion of this lesson, you should be able to:

  • Create a dataframe from vectors in your workspace
  • Load a built-in data frame using the function data()
  • Query and change variables and values within dataframes
  • Create new variables within data frames
  • Combine data frames
