[R] Pl. provide and Input for Kmeans

[Shalabh Gandhi]

Sir,

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:
library(mva)
data <- read.table('file1',header=TRUE,sep="\t")
centers <- read.table('file2',header=TRUE,sep="\t")
sink("output")
kmeans(data,centers,maxiters)
 

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

regards
shalabh
