Cut one subcluster from heatmap and then paste it using R

Hello Sir/madam,

I have total 304 DEG and i have clustered them using hclust and heatmap.2 is used to plot the heatmap. heatmap so this heatmap I have, contains Upper right side block as down regulated genes in cancer (green), lower right side block as up regulated genes in cancer (red).

  1. I want to cut only the lower right side block and then paste that block separately and also want to show the gene symbols to the side of heatmap.

I have refereed to the ComplexHeatmap, for split function.

  1. How to cut this red block using R and then paste it separately. without changing the cluster pattern which i have observed in the heatmap ? (no reclustering)

A sample R code will be helpful.

Thank you so much in advance.

If you literally just want to keep the right side block in its current form, then literally just edit the figure in a graphics editor. You could, for example, shade over the part of the heatmap in which you are not interested, and/or highlight the interesting part with a red box.

There does not have to be code for everything, of course.
