Scripts and Data

Toolchain:

	codeface-extraction
Codeface is a framework and interactive web frontend for the social and technical analysis of software projects.	codeface-extraction is a small extension to Codeface to extract and preprocess the version-control system data, e-mail data, and issue data.	coronet is a library to construct socio-technical developer networks based on various data sources in a configurable and reproducible way.

We developed a set of R scripts on top of Codeface and coronet for our analysis, which are available below. In order to run our scripts, you need to clone coronet (we have used our scripts with version 4.1) into a subdirectory of the scripts directory. Further information about the data format und input directories can be found in the README.md of coronet and also in the README.md delivered with our scripts.
