r - 使用 extrafont 将字体导入 R 时，如何解决“无字体名称”问题？

问题描述

我的 Windows 桌面 ( C:\Users\me\Desktop\Fonts) 上有一个文件夹，其中包含我想使用extrafont.

当我尝试使用导入字体时

library(extrafont)
font_import(paths = "C:/Users/me/Desktop/Fonts", prompt=FALSE)

我收到错误消息

基于此，我有两个问题：

  1. 我该如何克服这个No FontName. Skipping.问题？
  2. 试图告诉我的警告信息是什么，我需要对此感到担忧吗？

我会很感激任何帮助，非常感谢提前！

解决方案

正如@Moritz Schwarz 所提到的，问题可以追溯到Rttf2pt1.

根据此处提出的解决方案，将其降级到 1.3.8 将解决问题：

library(extrafont)
library(remotes)
remotes::install_version("Rttf2pt1", version = "1.3.8")
extrafont::font_import()
