The hierarchical clustering and the correlation matrix of 70 genes for the dataset from van’t Veer et al. (2002). The figure shows the clustering result (upper) and the correlation matrix (lower). There are 70 rows representing genes and 78 columns representing samples (upper) and the gene expression data ranging from green (negative) to red (positive) are displayed. Elements of the correlation matrix (lower) ranging from blue (negative) to yellow (positive) are displayed
