ggtext/减价标签中字体的故障排除

Question

我正在尝试使用ggtext::geom_richtext()来创建粗体/斜体文本(在Pop!OS导数22.04和R上)。我只得到纯文本(使用PNG或PDF或使用屏幕上的X11/cairo设备)。所有的输出在每种格式上看起来都很简单。(我也试过ragg::agg_png"了。)对于下一步在诊断/故障排除方面的尝试有什么想法吗？

library(ggplot2)
library(ggtext)
grDevices::X11.options(type = "cairo")
theme_set(theme_gray(base_size = 20))
test <- data.frame(x = 1:3, y = 2:4,
                   t = c("*a*", "**b**", "d"))
ggplot(test, aes(x,y)) + geom_richtext(aes(label= t), size  = 20)

ggsave("font_test.png")
ggsave("font_test.pdf")
system("eog font_test.png &")
system("evince font_test.pdf &")

Answer 1

应该先看看ggtext问题清单。我是第83期。

安装gridtext的开发版本

remotes::install_github("wilkelab/gridtext")

重新开始解决问题。
