This is a toy example of a reproducible data pipeline, based on Jenny Bryan's example for STAT 545A.

This shows how to create a small-but-automated analytical pipeline using a set of R scripts via source() AND using rmarkdown::render() on R Markdown files, without the help of RStudio's buttons.

Demonstration data: the number of words spoken by various characters in the Lord of the Rings trilogy, available here:
