add_whitespace

Randomly add whitespaces to the end of some values in
all or a subset of columns.

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.
