minex: Automatically Reduce Failing R Scripts to a Minimal Reproducible Example

Shrinks a failing R script to the smallest subset of statements that still triggers the same error, using the delta debugging algorithm of Zeller and Hildebrandt (2002) <doi:10.1109/32.988498>. Each candidate reduction is evaluated in a separate R process, so dependencies between statements and their side effects are respected. The result is a one-minimal example, in which removing any remaining statement makes the error disappear; this is the form most useful for bug reports and for questions on community forums. A general delta debugging routine and a helper for reducing data frames to the rows that reproduce a failure are also provided.
