Exercise

Import SPSS data with haven

The haven package can also import data files from SPSS. Again, importing the data is pretty straightforward. Depending on the SPSS data file you're working with, you'll need either read_sav() - for .sav files - or read_por() - for .por files.

In this exercise, you will work with data on four of the Big Five personality traits for 434 persons (Source: University of Bath). The Big Five is a psychological concept including, originally, five dimensions of personality to classify human personality. The SPSS dataset is called person.sav and is available in your working directory.

  • traits contains several missing values, or NAs. Run summary() on it to find out how many NAs are contained in each variable.
  • Print out a subset of those individuals that scored high on Extroversion and on Agreeableness, i.e. scoring higher than 40 on each of these two categories. You can use subset() for this.
