I have a dataset, called data
1) data.dist=vegdist(data) # get the bray-curits distance
2) prediction.strength(data.dist,M=10,clustermethod=pamkCBI,diss=TRUE,usepam=TRU)
# I hope to do the prediction.strength based on the bray-curits distance,but it not work.
Does anyone know how to do prediction.strength based on the bray-curits distance matrix and with pam clustering? Thank you!
i suppose that you have installed and loaded the required package for the analysis true?
the package is called ecodist

Thank you Andrea. The packages were already installed. I can get the distance matrix. But I have troubles in using the function “prediction.strength” to validate the clustering based on the distance. My aim is to get the prediction strength based on the bray-curits distance matrix with pam clustering.
