How to label only a few genes of interest in heatmap of bulk RNA-seq

Question

[Chris]

Hi all,

I used this code to make a heatmap

h <- Heatmap(mat.z, cluster_rows = T, cluster_columns = T, column_labels = colnames(mat.z),
             name = "Z-score", row_labels = sigs.df[rownames(mat.z),]$symbol)

Would you please tell me how to label only a few genes in this case? Maybe I need to modify row_labels but not sure exactly how. Thank you so much!

Thanks GenoMax! Do you know any bioinformatics volunteer position that I can apply? Unfortunately, I don't have any one senior near by, so I just learn by myself which is very slow.

A completely random segue, don't you think? Please keep the discussion on-topic.
