如何解决在ComplexHeatmap中更改图例的顺序
交叉发布： issues/557
我找不到在ComplexHeatmap中更改图例顺序的解决方案。
示例
library(ComplexHeatmap)
set.seed(100)
ha <- HeatmapAnnotation(foo = rep(c("gr1","gr2"),each = 5),annotation_label = c("col_an"))
ra <- HeatmapAnnotation(pt = rep(letters[1:2],which = "row",annotation_label = c("row_an"))
Heatmap(matrix(rnorm(100),10),name = "mat",top_annotation = ha,left_annotation = ra)
问题：如何按照从上到下的顺序排列图例？
-
col_an -
row_an -
mat

解决方法
这是作者提供的解决方案：
set.seed(100)
ha <- HeatmapAnnotation(foo = rep(c("gr1","gr2"),each = 5),annotation_label = c("col_an"),annotation_name_side = "left")
ra <- HeatmapAnnotation(pt = rep(letters[1:2],which = "row",annotation_label = c("row_an"))
ht = ha %v% Heatmap(matrix(rnorm(100),10),name = "mat",left_annotation = ra)
draw(ht,merge_legend = TRUE,column_dend_side = "top")
