I am not able to increase the size (height) of the column annotations of the heatmap. I tried annotation_height, height, and re_size but none of them seems to work.

df<-featuresFilt[,c("Tissue","New.Diagnosis","Age","Sex","Race","TumorSite")]
colnames(df)<-c("Tissue","Diagnosis","Age","Sex","Race","TumorSite")
ha = HeatmapAnnotation(
  #df = features[,c(5,6,7,13,15)],
  #df = featuresFilt[,c(3,4,5,6,13,7)],
  df = df,
  col = list(Tissue = col_tissue,
             Diagnosis = col_disease,#c("Normal" = "black","Adrenocortical carcinoma" = "red"),#col_cluster,#c("Adrenocortical carcinoma" = "red", "Normal" = "black", "Carcinoid tumor" = "blue","Gastrointestinal stromal tumor"="brown"),
             Age = col_age,
             Sex = genderColor,#c("Male"="turquoise","Female"="brown"),
             #RIN = col_rin,
             Race =raceColor,#c("White"="#B35806","Unknown"="#FDBC6B","Other"="black","Black or African American"="#E3E4EF","Native Hawaiian or Other Pacific Islander"="#8D81B6","Asian"="blue"),
             TumorSite=tumorSiteColor#c("Metastasis"="turquoise","Primary Site"="brown","Recurrence"="black")
             #cluster = col_cluster
  ),
  #annotation_height = unit(rep(6,6), "mm"),
  #height = unit(36,"mm"),
  #annotation_name_gp =  gpar(fontsize = 14,fontface = 2),
  #annotation_legend_param = list(title_gp = gpar(fontsize = 15, fontface = 2),labels_gp = gpar(fontsize = 12)),
  #annotation_height = unit(rep(2,6), "cm"),
  annotation_height = c(TumorSite = unit(8, "mm"),Diagnosis=unit(8, "mm"),Age=unit(8, "mm"),Sex=unit(8, "mm"),Race=unit(8, "mm"),TumorSite=unit(8, "mm")), height = unit(48, "mm")
)

print(ha)
