extract cluters of genes from pheatmap and generate independent pheatmaps

Question

[Maria]

Hi everyone!

I have gene expression data, and I generated a pheatmap where I can see very well two clear cluster of genes, up and downregulated. Since I have a lot of significant genes, around 1300 genes, and any visual inspection is problematic, so I would like to split the pheatmap and generate two separated pheatmaps, like I show you in the next image.

Any suggestions are welcome! Thanks!
