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. When no statement can be removed, because
the failure is nested inside a function body, reduction continues within
the surviving statements. A general delta debugging routine and a
helper for reducing data frames to the rows that reproduce a failure are
also provided.
