Using the intrinsic gene set, hierarchical clustering was performed on all 65 observations (left panel) and on only the 62 observations that were assigned to one of the four classes (right panel). Note that the classes identified using all 65 observations are largely lost in the dendrogram obtained using just 62 observations. The four classes are basal-like (red), Erb-B2 (green), normal breast-like (blue), and ER+ (orange). In the left-hand panel, observations that do not belong to any class are shown in light blue.
