[BioC] How should I interpet heat map with dendrogram..

[Saurin Jani]

Hi,

is there any paper or explanation of how should I
interpret heatmap with dendrogram. 

symbs <- getSYMBOL(myFeatureGenes,"moe430a");
symbs <- ifelse(is.na(symbs),myFeatureGenes,symbs);


row.names(esetFeatureX) <- symbs;
colnames(esetFeatureX) <- samples;

jpeg(filename="RMA_heat_map1.jpeg",width=1000,height=1000);
heatmap(esetFeatureX,col = dChip.colors(50),main =
"Heatmap of top ranked genes ");
dev.off();

thanks
Saurin
