I am preparing data matrix for siggenes as follow:

data=read.table("data.txt", skip=1, header = F)
data=as.matrix(data)
data[1:3, ]

       V1   V2   V3   V4   V5   V6   V7   V8
[1,] 0.26 0.21 0.37 0.47 0.43 0.35 0.15 0.50
[2,] 0.21 0.22 0.40 0.40 0.28 0.23 0.17 0.40

is it ok to have the defualt column names? if not, how can I suppess it when I 
use read.table?
Thank you
