  This technical report accompanies a research article that empirically studies
the problems related to inter-repository package dependencies in the R
ecosystem of statistical computing, with a focus on R packages hosted on CRAN
and GitHub. The current report provides supplementary material, reproducing an
anonymised and sanitised version of e-mail interviews that have been conducted
in November 2015 with five active R package maintainers. The goal was to gain a
better understanding in how R package maintainers develop and distribute their
packages through GitHub and CRAN. All five interviewees were actively
maintaining packages on GitHub, some were also active on CRAN. They have been
selected based on their profile (the number of R packages they maintain on
GitHub and/or CRAN) as well as their gender (three interviewees were male, two
were female).
