Question

这是一个最小的工作示例。

output:
    pdf_document
title: "Testing Rmarkdown"

```{r,comment = NA}

Gender <- gl(2,1000,labels = c("Men","Women"))
SmokerM <- sample(c("Y","N"),1000,replace = T , prob = c(.3,.7))
SmokerW <- sample(c("Y","N"),1000,replace = T , prob = c(.5,.5))
Smoker <- c(SmokerM,SmokerW)

mydata  <- data.frame(Gender,Smoker)
table(mydata$Gender,mydata$Smoker)

```

This is a text in the body of the document.What font is this ? What is
font for the output of table ? How can we change these 2 fonts ? What 
other categories of items are there in an Rmarkdown which have different
fonts ?

我的查询如下：Rmarkdown文档的默认字体是什么？如何更改它们？

在研究这个问题时，我遇到了这个页面：

[Pandoc变量] [1] http://pandoc.org/MANUAL.html#variables-for-latex

在Rmarkdown中描述4类输出有4种字体（mainfont / sansfont / monofont / mathfont）是否正确？它们的默认值是什么？如何更改它们？

Answer 1

创建PDF文件时使用LaTeX。 LaTeX中使用的默认字体是Computer Modern。有多种方法可以更改LaTeX使用的字体，但如果不知道LaTeX，则所需的名称通常不直观。更简单的解决方案是将mainfont等与xelatex或lualatex一起用作引擎。您可以使用平台的标准字体名称在yml标题的顶层定义这些选项。这里使用Liberation Serif作为主要字体的示例文档：

第一个表使用单声道字体，即Liberation Mono，因为它是正常的R输出。第二个表再次使用主字体。有关详细信息，请参阅documentation。
