What is a data frame?

A data frame refers to a two-dimensional array-like structure or table that is made up of rows and columns, which is typically used for storing data in R Studio using the R programming language.

In Computer programming, a data frame is a list of vectors that are all equal in length, and each column consist of values of one variable while each row consist of a set of values from each column.

The executable code in R Studio.

In this scenario, the code chunk that would be used to create a data frame that combines the two columns into a single column (phone_number) is:

• unite(customers, "phone_number", area_code, phone_num, sep="-"
