在ComplexHeatmap中，如何改变anno_barplot()标题的角度？

Question

我使用 R 包，

complexheatmap

来绘制热图。 这是我的代码：

aa <- rowAnnotation("log10(FDR)" = anno_barplot(fdr), 
                    "log2(Fold Change)" = anno_barplot(fc, gp = gpar(fill = fc_color(fc))),
                    width = unit(3, 'cm'),
                    gap = unit(10, "points"))
Heatmap(matrix = mtx, 
             border = T, 
             column_order = ordered_sample, 
             heatmap_legend_param = list(title = "", 
             legend_height = unit(4, "cm")), column_names_rot = -90, 
             row_names_gp = gpar(fontsize = 8), 
             column_names_gp = gpar(fontsize = 8), 
             clustering_method_rows = "ward.D2", 
             name = "Scale(exp)", 
             cluster_column_slices = T, row_split = rr_,
             cluster_rows = T, 
             cluster_columns = F, 
             clustering_method_columns = "ward.D2",
             col = htmp_color, right_annotation = aa
        )

我的问题是如何将

log10(FDR)

转90度？ 这样两个Barpl图的标题就不会重叠

Answer 1

如果能提供一些样本数据就更好了。使用另一个示例，

annotation_name_rot = 90

似乎可以解决问题（旋转

foo2

和

bar2

右下角）：

library(ComplexHeatmap)

set.seed(123)
mat = matrix(rnorm(100), 10)
rownames(mat) = paste0("R", 1:10)
colnames(mat) = paste0("C", 1:10)
column_ha = HeatmapAnnotation(foo1 = runif(10), bar1 = anno_barplot(runif(10)))
row_ha = rowAnnotation(foo2 = runif(10), bar2 = anno_barplot(runif(10)), annotation_name_rot = 90)
Heatmap(mat, name = "mat", top_annotation = column_ha, right_annotation = row_ha)
