when I focus on a cluster, I loose all the labels

[FrancescaLodi]

Hello,

I have made a big heatmap with 60 cell subtypes, however if I want to focus on just one, I loose all the labels text.
Here below what I tried to do and what I obtained. Thanks a lot!

pheatmap(mat["Tcells_XX",], display_numbers = T, cluster_rows=F, cluster_cols=F, annotation_names_row = T, annotation_names_col = T, show_rownames = T, show_colnames = T)
