Question

在较旧的R版本中，我能够用中文书写并插入字符标题，轴等字符，如ggtitle("你好")。

现在我更新到R 3.4.1并且不再起作用了，所以我读到了extrafont和showtext。 OS X和Windows中的两个选项部分直接来自R脚本（一些缺少的字符），但Rmd文档根本不起作用。

你如何绕过这个问题？

以下是我在下载和安装Google的Noto Sans（中文版）后尝试的一个虚拟示例：

R脚本：

library(readr)
library(dplyr)
library(ggplot2)
library(forcats)
library(showtext)
font_add("notosans","C:\\Windows\\Fonts\\notosansCJK-REGULAR.TTC")
showtext_auto()
