idaifieldR imports data from Field Desktop into R. This supplement contains the R-project used in the paper "R wie in: Reproduzierbar: Auswertung von Daten aus Field Desktop mit idaifieldR" (DOI: 10.34780/068b-q6c7) (https://zenon.dainst.org/Record/003041245), demonstrating the packages core functionality. Alongside the RMarkdown-file used to generate the paper itself and a tutorial on using package the supplement contains a small dataset of attic red- and black-figure pottery found at the area of the Church of St. Michael / Dionysos Sanctuary in Miletus in Asia Minor in the form of a csv-file. Variables in the dataset are: inventory number, context, trench, group, shape, dating and catalogue number. The fragments are published in "N. Kunisch, Funde aus Milet Teil 3, Die attische Importkeramik (Berlin/Boston 2016)" (https://zenon.dainst.org/Record/001471948). A backup of a test project with artificial data for Field Desktop is also included in the supplement, and can be used to follow the tutorial mentioned above.
