R codes used in full-text cluster analysis of publications in systematic literature review on food systems transformations

This are the R codes used to generate the research clusters and its respective plots in the paper "What are the ingredients for food systems change towards sustainability? - Insights from the literature" by Weber, Hanna; Poeggel, Karoline; Eakin, Hallie; Fischer, Daniel; Lang, Daniel; von Wehrden, Henrik; Wiek, Arnim, which is currently under revision. The code groups publications into different clusters based on co-abundancy of words. The main code is the file “using_ginko_explained”, which sources the codes “statistics” and “scopus”, as well as the csv-file "Conceptual_Vocabulary".

This code is a preliminary version. The authors are currently working on a cleaned-up version of the code for publishing it as an R-package.
