Question about list of heatmaps

[ShinyFabio]

Hi jokergoo, I have a question about the dendrogramms. I have multiple heatmaps generated with a loop for. Each of them has its own legend and its own row clustering (only row). Every loop ends in this way:

ht_list = ht_list + ComplexHeatmap::Heatmap(....)

So in every cycle I add another heatmap. The resulting list of heatmaps is then printed with the draw() function. Now my question is: how are combined the different row clusterings since in the end I have just one dendrogramm?

[jokergoo]

By default it is controlled by the first numeric heatmap, but you can manually control it by setting the "main heatmap":

draw(ht_list, main_heatmap = ...)

Ok, so it's a bit misleading in my case. Do you know if it's possible to have a dendrogram that takes into account all the heatmaps? Or at least to render a dendrogram for each heatmap?

[jokergoo]

Then how do you correspond between heatmaps? e.g. row i in the first heatmap should correspond to the same thing for row i in the second heatmap (after the clustering)?

If you want to apply clustering for all heatmaps, then it does not make sense to "concatenate" these heatmaps, while instead, these heatmaps will just become different plots.

Okay so I misunderstood the way complexheatmap concatenate them. So my solution could be to render different heatmaps and taking them separated without using ht_list. Of course if I want to use InteractiveComplexHeatmap, I will have different interactive heatmap outputs, correct?

Yes, they are basically "different plots".
