“Old Techniques for New Times”: the RMaCzek package for producing Czekanowski’s diagrams

SummaryInspired by the MaCzek Visual Basic program we pprovide an R package, RMaCzek, that produces Czekanowski’s diagrams. Our package permits any seriation and distance method the user provides. In this paper we focus on the “OLO” and “QAP_2SUM” methods from the seriation package. We illustrate the possibilities of our package with three anthropological studies, one socioeconomic study and a phylogenetically motivated simulation study.
