Getting ready

In R, a vector is simply a collection of values with the same type; it could be all character, numeric, or logical. For example, it could contain names of places/countries, it could contain the number of hours a person spends on the internet over the last seven days, or it could also contain whether a group of people has a certain disease or not (true/false).
