Hi Using goCluster, i can obtain a hierarchical clustering display with a goCluster object and a visualization parameter (clusterVisualHclust). Now i want to recuperate the go ids printed on the right of the graph into a vector in order to display graph with one of these specific GO terms. How can i recuperate these ids ? Regards.
