R过热包热图：更改底轴标签的字体大小

Question

我想增加R中superheat包创建的热图的底轴标签大小。

根据vignette，可以通过bottom.label.size参数完成此操作。但是，这不会改变我的字体大小（请参阅下面的RSession），但只会更改标签写入框的边距：

library(dplyr)
library(superheat)

matrix(1:9, ncol = 3) %>% superheat(bottom.label.size = 0.1)

matrix(1:9, ncol = 3) %>% superheat(bottom.label.size = 0.05)

有谁知道如何控制这个？这是一个错误还是我错过了什么？

Answer 1

matrix(1:9, ncol = 3) %>% superheat(bottom.label.size = 0.1, bottom.label.text.size = 10)
