Would like to know what sort of input matrix are taken by the kmeans function
defined in mva library of R application. As per the documentation for the
Kmeans it takes the following 2 data sets:

1) data
2) centers

The commands to be executed in R are as follows:
data <- read.table('file1',header=TRUE,sep="\t")
centers <- read.table('file2',header=TRUE,sep="\t")

Can you please help me in providing with the data and center values. The data
I am currrently using gives me an error -- empty cluster: try better set of
initial centers. Number of clusters centers mush lie between 1 and nrow(n).

Waiting for your reply
