In christinschaetzle/DiaHClust: Hierarchical clustering method for identifying stages in language change

Description

This package contain functions which implement the DiaHClust methodology (Schaetzle and Booth 2019) for the identification of stages in historical linguistic change. DiaHClust is based on the iterative application of Variability-based Neighbor Clustering (VNC, Gries and Hilpert 2008, 2012) in combination with a cluster validation process using silhouette values in order to provide a multi-layered perspective on language change, from text-level to broader time stages, while also respecting outliers and genre effects.

Examples

icelandic=data(icelandic)
icelandic.cor=cor(icelandic[,-1])  #[,-1] because rows are labeled
icelandic.dist=dist(icelandic.cor)

icelandic.vnc=vnc(icelandic.dist, method="average")
plot(icelandic.vnc, hang=-1) #plotting the resulting dendrogram

#cluster validation for identification of time stages

#Iterative clustering with DiaHClust methodology
icelandic.diahclust=diahclust(optimal, icelandic[,-1], method="average")
