Question

我正在努力改变我的pdf文件的字体。我的计算机上没有Helvetica所以我无法编译.pdf（html完美无缺）。我相信我的Rmarkdown编码不起作用，但它与建议的here相同。 LaTeX安装正常，我可以使用Lyx的XeLaTeX进行编译。

据我了解，Calibri字体已加载

fonts()[grepl('Calibri',fonts())]
[1] "Calibri"       "Calibri Light"

我一直在调整cannot load afm file 'Helvetica.afm'错误。这是我的会议

更新

错误在于R代码块。如果我编织除了R块之外的所有东西都可以工作

this is my test  

I can write anything here and it will render **perfectly**  

```{r}
plot(mtcars)
```

processing file: test.Rmd
