    city temperature
    Beijing 35
    Lagos 88
    Paris 42

    To avoid typo’s

    You can copy paste the cities and temperatures from here
    cities: "Beijing", "Lagos", "Paris", "Rio de Janeiro", "San Juan", "Toronto"
    temperatures: 35, 88, 42, 84, 81, 30

  2. Use the names function and the objects from question 1 to name the temp vector in a way that every temperature is associated with its corresponding city name.

    Hint

    run ?names in RStudio for more information on how to use the function.

  3. Use the [ and : operators to access the temperature of the first three cities of the named temp vector. put your result in an object named temp_13.

  4. Use the [ operator and a vector to access the temperature of Paris and San Juan of the named temp vector. put your result in an object named temp_ps.

NOTE Make sure you add the city and temperature elements in the same order as in this description!
