What is the number format, and how to identify the values as numeric/integer types ?


I agree that this was not explained sufficiently in the exercise. I needed to Google to figure this exercise out. c() stands for concatenate and is used regardless of the type of data (from the example and without explanation I assumed this was how we were defining the data type as character). The values are defined as numeric, simply by using numbers and not surrounding them with quotes.


Arguably, this lesson should require a phone number as a vector of character strings (due to potential for leading zeros, eg 555-111-0981
The form of the phone number is not internationally friendly - perhaps a different type of data that is a list that can be represented as numbers (date of birth perhaps).

The type of elements in my vector were “double”. What does this mean ?


Very basic question but why in the example are the months in quotation marks but in the numeric solution we don’t include quotes? Thanks!!
