Meltem Ballan introduces data frames in R:
Our first data frame constrained of seven vectors, Customer_Id, loan_type, First_Name, Last_name, Gender, Zip_code and amount.
NOTE: R is case sensitive. That is why I have used lower and upper case for you to practice.
After we run the lines we want to see how our first data frame looks. Following command will suffice that need:
>View(my_first_df)
If you’re coming from a SQL background, data frames are tables. Well-formed (“clean”) data frames more or less follow first normal form.
