Rmarkdown font size and header
提问by theamateurdataanalyst
I recently opened a standard Rmd file without editing anything. The default file looks like this:
我最近打开了一个标准的 Rmd 文件，没有编辑任何东西。默认文件如下所示：
Untitled.rmd
无题.rmd
---
title: "myfile"
author: "Me"
date: "May 25, 2015"
output: html_document
fontsize: 12pt

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.
When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
```{r}
summary(cars)
```
You can also embed plots, for example:
```{r, echo=FALSE}
plot(cars)
```
Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
I wanted to create an html file corresponding to the above file so in a separate R script I did the following:
我想创建一个与上述文件相对应的 html 文件，因此在单独的 R 脚本中，我执行了以下操作：
knit('Untitled.Rmd', 'doc.md')
markdownToHTML('doc.md', 'testing.html',header = TRUE)
For some reason the font size doesn't work and the header information that I was hoping for doesn't appear in my testing.html. Anyone know why this is happening?
由于某种原因，字体大小不起作用，我希望的标题信息没有出现在我的 testing.html 中。有谁知道为什么会这样？

This is what I used to control font size and color in an R-markdown file. It basically overrides the CSS style sheets without having to create a new file. The example changes the sizes of the headers and titles, as well as the inline text and the R-code text, and sets some colors as well.
这是我用来控制 R-markdown 文件中字体大小和颜色的方法。它基本上覆盖了 CSS 样式表，而无需创建新文件。该示例更改了标题和标题的大小，以及内联文本和 R 代码文本，并设置了一些颜色。
In my case I needed to pack more information into a document that had a specified number of pages so I made everything smaller.
就我而言，我需要将更多信息打包到具有指定页数的文档中，因此我将所有内容都缩小了。

</style>
# H1 Header
Some body text
## H2 Header
More body text

```
