duplicate_rows

Duplicate rows and insert them into the dataframe in order or at random

For the purposes of teaching, it is often desirable to show
examples of working with messy data and how to clean it. This R package
creates messy data from clean, tidy data frames so that students have a
clean example to work towards.
