如何调整复杂热图中轴标签的字体大小？

Question

我正在使用ComplexHeatmap在 R 中创建热图。我在这里重新创建了一个小热图。我无法从文档中弄清楚如何调整 x 轴上文本的字体大小。

a = matrix(1:9, nrow = 3, ncol = 3)
rownames(a) = c("alphabet","xylophone","tornado")
colnames(a) = c("c1","c2","c3")

my_heatmap = ComplexHeatmap::Heatmap(
        matrix = t(a),
        col = RColorBrewer::brewer.pal(9, "RdBu"))

这段代码产生这样的结果：

我想调整c("alphabet","xylophone","tornado")文本的字体大小，使其小得多。我该怎么做呢？

You can use row_names_gp and column_names_gp to adjust y-axis and x-axis labels, respectively.

# if (!requireNamespace("BiocManager", quietly = TRUE))
#       install.packages("BiocManager")
# BiocManager::install("ComplexHeatmap")
#
# library(ComplexHeatmap)
# library(grid)

# if (!requireNamespace("BiocManager", quietly = TRUE))
#       install.packages("BiocManager")
# BiocManager::install("ComplexHeatmap")
#
# library(ComplexHeatmap)
# library(grid)
