I have been working on biclustering. I wrote a script to generate gene expression data with implanted clusters, but only with zeros and ones. For example

0    s0    s1    s2    s3    s4    s5    s6    s7    s8    s9    
g0    1    1    0    0    1    1    0    0    0    0    
g1    1    1    0    0    1    1    0    0    0    0    
g2    1    1    0    0    1    1    0    0    0    0    
g3    0    0    0    1    1    1    0    0    0    0    
g4    0    0    0    1    1    1    0    0    0    0    
g5    0    0    0    1    1    0    0    0    0    0    
g6    0    1    1    0    0    0    0    0    0    0    
g7    0    1    1    0    0    0    0    0    0    0    
g8    0    1    1    0    0    0    0    0    0    0    
g9    0    0    0    0    0    0    0    0    0    0

I am wondering if anyone has snippet for generating expression such implanted cluster with real values.
