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:

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

new version of e1071 on CRAN
...in directory
`docs/' (svmdoc.pdf).
o classAgreement now features an option to match factor levels
o updated API design for the fuzzy clustering functions
(cmeans, cshell, scaclust). Documentation updates and function
name changes (cmeanscl -> cmeans, validity.measures -> fclustIndex)
