I would like to generate at dataset that looks something like this
1 US US1001
2 GB GB3400
3 DE 4DE497
4 CE EAPO68
Where the first column follows a certain pattern, in this case two letters. The next column the entries start with the same two letters. There are also some that don't obey the rule, such as entry 3 and 4. I am not sure how to do this. Any help greatly appreciated

You'll need to show what you've tried and what is not working. People will help you solve a problem, but they will not design a solution. The part about some not obeying the rule is also vague.

Try samplingLETTERSand integers from 1000 to 9999, and then concatenating them usingpaste. Also consider usingapplyinstead ofx$newcol <- sample(LETTERS, 2)to avoid populating the columns with identical values

Do you mean you need to create a dataset with random values/factor/value-factor?

Try sampling
LETTERS and integers from 1000 to 9999, and then concatenating them using paste. Also consider using apply instead of x$newcol <- sample(LETTERS, 2) to avoid populating the columns with identical values– 12b345b6b78
