r - 如何修复 R 图中的字符编码？

Question

最近，我用 anaconda 安装了 R。显然，一切正常。但是，当我绘制一些带有数字的奇怪框而不是字母和数字时。我认为我的字符编码有问题。

我该如何解决这个问题？我附上了我的问题的示例图。

我的 sessionInfo() 输出是：

另外，我发现我无法安装 Cairo 库

checking for ATS font support in Cairo... no
configure: CAIRO_LIBS=-lcairo
checking for library containing deflate... -lz
checking whether Cairo programs can be compiled... configure: error: Cannot compile a simple Cairo program. See config.log for details.
ERROR: configuration failed for package ‘Cairo’
