1.3 A quick refresher

If you haven’t used R for a while, or are a relatively new R user, then take a moment to remind yourself about the various data types in R. Try creating an example of the different types of structure using various data types:

• Numeric
• Integer
• Logical
• Character
• Complex

And the structures in which those data types can be stored:

• Vector
• Matrix
• List
• Data frame
• Factors (not really a structure!)
