I am using R heatmap.2.

Take a look at the above heatmap generated by heatmap.2. There are 5 big clusters of rows: 1 yellow/red, 2 red/yellow, 3 yellow/red, 4 red/yellow, 5 yellow/red.

Shouldn't the yellow/red clusters cluster together, and red/yellow ones cluster together, and then form the biggest cluster?

The R code is as follows:

```
heatmap.2(data.matrix(heatmapEntries), main="xxx", dendrogram="row", Rowv = TRUE, Colv=FALSE, margins=c(11.3333333333333,5), scale="row", trace = "none", cexRow=1, lhei=c(1,10), lwid=c(1,3));
```

Thanks in advance!
