fclustIndex(package e1071) error: LaPack Routine dgesv
Dear colleagues: Despite my best efforts, I have not been able to understand/overcome an error message I received while running the fclustIndex command in package e1071, which produces validity measures for the fuzzy c-means clustering algorithm. I am relatively new to R-- and still depend heavily on Rcmdr-- and so I apologize in advance if there is an obvious answer to my question: My code is as follows: library(e1071) Dataset...

fclustindex, e1071 package
...>ra.flcust6<-cmeans(ra,6,iter.max=100,verbose=F,dist="euclidean",method="cmea ns",m=1.7,rate.par=NULL,weights=1) I would like to calculate the value of all the fuzzy validity measures using the flcustIndex function. However it returned the following error: > fclustIndex(ra.flcust6,ra,index="all") Error in solve.default(scatter[, , i]) : Lapack routine dgesv: system is exactly singular Please could anyone explain what this means and what I have done wrong? thanks Caroline Wallis [[alternative HTML version deleted]]
