fclustindex, e1071 package
...les - depth and velocity. I used fuzzy cmeans
to create 6 fuzzy classes.
>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
