复杂热图中的 RowAnnotation 字体

Question

我有一个热图，其中包含数据框中的一些基因和值。我还有一个向量，其中的名称与 df1 相同，但向量中有另一个标识符。我想用第一个 df 制作一个热图，并将向量中的标识符用作行注释。我已经走到这一步了：

我成功制作了热图，但我无法更改行注释的字体大小。有人知道该怎么做吗？代码如下：

ha = HeatmapAnnotation(text = anno_text(vector), which = "row", gp = gpar(fontsize = 5, fontfamily = "sans", fontface = "bold"))

heat.gen.k = Heatmap(tf.log, width = unit(4, "cm"),
                   km = 6, 
                   cluster_columns = F, 
                   show_row_names = F, 
                   row_title_rot = 0, 
                   row_title_gp=gpar(fontsize=5),
                   row_gap = unit(1.25, "mm"), 
                   name = "Log2FC", 
                   column_title = "Resistant - Susceptible",
                   column_title_gp = gpar(fontfamily = "sans", fontsize = 16), 
                   col = heat.col,
                   right_annotation = ha)

Answer 1

我知道自发布以来已经一年多了。

我锻炼而不是 right_annotation = ha

您需要使用：

row_names_gp = gpar(fontsize = 5, fontfamily = "sans", fontface = "bold")

heat.gen.k = Heatmap(tf.log, width = unit(4, "cm"),
                 km = 6, 
                 cluster_columns = F, 
                 show_row_names = F, 
                 row_title_rot = 0, 
                 row_title_gp=gpar(fontsize=5),
                 row_gap = unit(1.25, "mm"), 
                 name = "Log2FC", 
                 column_title = "Resistant - Susceptible",
                 column_title_gp = gpar(fontfamily = "sans", fontsize = 16), 
                 col = heat.col,
                 row_names_gp = gpar(fontsize = 5, fontfamily = "sans", fontface = "bold"))
