[R] problems of R+Weka+Xmeans

Hi guys,

I have one problem when I use R+Weka+Xmeans. I set the parameters for Xmeans as follows:

xc.control <- Weka_control(I=10,M=1000,J=1000,L=1000,H=2000,B=1.0, C=0.5,D="weka.core.EuclideanDistance",S=20) xc <- XMeans(data,control=xc.control)

Here I set the L as 1000. according to Xmeans in Weka:

-L <num> minimum number of clusters

However, no matter how I change L, it always gives me 2-clusters (rather than at least 1000 clusters).

And the number of entries in data is much more than 1000.

Does anyone know what happens here and how I can fix it?

Thanks
