I am trying to generate kmean of 10 clusters for a 165 x 165 matrix.

i do not see any errors known to me. But I get this error on running the script

Error: empty cluster: try a better set of initial centers

the commands are

M <-matrix(scan("R_mutual",n = 165 * 165),165,165,byrow = T)

cl <- kmeans(M,centers=10,20)
len = dim(M)[1]
....
....

I ran the same script last night and it was working prefectly. I have not made any changes at all !!!And this is very strange. This evening when I ran the same script i am getting this error. My matrix file is also untouched.

Can any one let me know how to go about this. I must generate 10-mean clusters
Is there anyother way of doing it ? and how to avoid such error in future?
