刪除 Markdown 輸出中的換行符

Question

我想將data.table的內容打印到 R-Studio 的 Markdown 文檔中。 但是，輸出有點寬，所以我減少了字體，如下所述： Rmarkdown 中的代碼塊字體大小與 knitr 和乳膠

然而，即使將字體減小到很小，盡管有足夠的空間讓列相鄰，但換行符仍然存在。 我想知道這是如何實現的。

title: "mwe"
output: pdf_document

```
{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
library(data.table)
dat <- data.table(id=1:5,num=31:35,text=c("a","b","c","d","here you can find some long text to artificially widen this text column and demonstrate the problem"))
```
Here is some text.

\tiny
```{r}
dat

```

數據[5]

Answer 1

檢查?options並查找控制每行打印列數的參數width ：

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
library(data.table)
dat <- data.table(id=1:5,num=31:35,text=c("a","b","c","d","here you can find some long text to artificially widen this text column and demonstrate the problem"))
```

\tiny
```{r}
dat
```

```{r}
options(width = 120)
dat
```
