CHANGES IN reproducer VERSION 0.3.1

NEW FEATURES

• Data set: MadeyskiLewowski.IndustryRelevantGitHubJavaProjects20191022 - over 15% of entries present in this data set is not present in the previous data set MadeyskiLewowski.IndustryRelevantGitHubJavaProjects20190324 due to moved time windows for the project creation and last push dates.

UPDATED FEATURES

• Updated function searchForIndustryRelevantGitHubProjects - now supports flexible creation date and last push thresholds (enabling the script to better support researchers interested in gathering evolving data sets).

CHANGES IN reproducer VERSION 0.3.0

NEW FEATURES

• Functions including computational procedures used to reproduce the main findings, e.g., tables, in a joint paper: Barbara Kitchenham, Lech Madeyski, Pearl Brereton, “Meta-analysis for Families of Experiments in Software Engineering: A Systematic Review and Reproducibility and Validity Assessment”: transformHgtoZr,
• Function to search for industry relevant software projects available from GitHub related to a report: Lech Madeyski, “Training data preparation method,” tech. rep., code quest (research project NCBiR POIR.01.01.01-00-0792/16), 2019; as well as a paper: Tomasz Lewowski and Lech Madeyski, “Creating evolving project data sets in software engineering”, 2019: searchForIndustryRelevantGitHubProjects
• Data set: MadeyskiLewowski.IndustryRelevantGitHubJavaProjects20190324

UPDATED FEATURES

• Updated function reproduceTablesOfPaperMetaAnalysisForFamiliesOfExperiments

CHANGES IN reproducer VERSION 0.2.1

UPDATED FEATURES

• Fixed version of the package in README
• Added warning to the ExtractMAStatistics function: it works with metafor version 2.0-0, but changes to metafor’s method of providing access to its individual results may introduce errors into the function.
