Dendrogram for GDS3216. The study associated with this data set measured the response A. thaliana seedling roots have to salinity in a time-course experiment. The nodes are colored according to the colors of the spectrum: 0 hours/control (red), 0.5 hours (orange), 1 hour (yellow), 4 hours (green), 16 hours (blue), and 32 hours (violet). Manhattan distance with average linkage has been chosen. The top dendrogram is the default one produced by agnes. By swapping the branches at the internal nodes indicated in red in this dendrogram, the one below is produced.
