Description: Uses provenance post-execution to help the user understand
and debug their script by providing functions to look at intermediate steps and
data values, their forwards and backwards lineage, and to understand the
steps leading up to warning and error messages. 'provDebugR' uses
provenance produced by 'rdtLite' (available on CRAN), stored in PROV-JSON format.

Title: Compare Provenance Collections to Explain Changed Script Outputs

Inspects provenance collected by the 'rdt' or 'rdtLite' packages,
or other tools providing compatible PROV JSON output created by
the execution of a script, and find differences between two provenance
collections. Factors under examination included the hardware and
software used to execute the script, versions of attached libraries,
use of global variables, modified inputs and outputs, and changes
in main and sourced scripts. Based on detected changes, 'provExplainR'
can be used to study how these factors affect the behavior of
the script and generate a promising diagnosis of the causes of different
script results. More information about 'rdtLite' and associated tools is available
at <https://github.com/End-to-end-provenance/> and Barbara Lerner,
