Unfortunately, I am unable to correctly use cl_ensemble and cl_agreement (package: clue). Here is what I am trying to do: library(clue) ## Let p1..p4 be four partitions of the kind p1=c(1,1,1,2,2,2,3,3,3) p2=c(1,1,1,3,2,2,3,3,2) p3=c(1,2,1...

In a first step, I want to use a single variable for the partitioning process. As the center-matrix I use the objects that belong to the cluster I found with the...
