The row name labels of my heatmap are genes. The default color for the column names and row names are
black, however, I would like to change some gene names to different colors (for example,
red for up-regulated genes and
blue for down-regulated genes, similar to volcano plot)
It seems that there is no function in pheatmap can change this setting. The most possible one is
labels_row to custom labeled row names. Does anyone know how to custom row name color?
pheatmap(test, cellwidth=30, , cellheight = 10, angle_col = 45, annotation_col = df, labels_row = ???)
