should red and yellow be swapped?

Issue: Should yellow and red be swapped in the wording here? Based on both the row mean plot and the column mean plot, my understanding is that red is the higher value.

  |===========                                                         |  17%
| Now consider this picture. On the left is an image similar to the heatmap
| of dataMatix you just plotted. It is an image plot of the output of
| hclust(), a hierarchical clustering function applied to dataMatrix. Yellow
| indicates "hotter" or higher values than red. This is consistent with the
| pattern we applied to the data (increasing the values for some of the
| rightmost columns).

...

  |=============                                                       |  19%
| We see immediately the connection between the yellow (hotter) portion of
| the cluster image and the higher row means, both in the upper right portion
| of the displays. Similarly, the higher valued column means are in the right
| half of that display and lower colummn means are in the left half.

Thanks,
