在 Quarto 上設置代碼塊大小 pdf output

Question

知道如何在 Quarto pdf output 上為代碼塊設置小尺寸嗎？ 我不希望我的代碼與我的文本具有相同的大小，但我無法在文檔開頭的設置中找到參數，也無法在 R 代碼塊中找到指定字體大小的參數。

Answer 1

您可以編寫一個knitr-hooks來創建一個塊選項（假設size ）來控制代碼塊（源代碼 + 塊輸出）的字體大小。

title: "Small Font Size for Code chunk"
format: pdf
---

## Quarto

```{r}
#| echo: false

default_chunk_hook  <- knitr::knit_hooks$get("chunk")

latex_font_size <- c("Huge", "huge", "LARGE", "Large", 
                     "large", "normalsize", "small", 
                     "footnotesize", "scriptsize", "tiny")

knitr::knit_hooks$set(chunk = function(x, options) {
  x <- default_chunk_hook(x, options)
  if(options$size %in% latex_font_size) {
    paste0("\n \\", options$size, "\n\n", 
      x, 
      "\n\n \\normalsize"
    )
  } else {
    x
  }
})

```

Answer 2

您可以使用 LaTeX 字體選項在本地執行此操作：

---
title: "chunk-size"
format: pdf
editor: visual
---

\tiny
```{r}
summary(mtcars$mpg)
```
\normalsize

您可以使用Huge > huge > LARGE > Large > large > normalsize > small > footnotesize > scriptsize > tiny 。
