R-Markdown-kableExtra软件包-format ='latex'不起作用 [英] R-Markdown - kableExtra package - format = 'latex' not working

问题描述

使用kableExtra文档.在RMardown中，我正在运行:

Using the kableExtra documentation. inside RMardown I am running:

```{r}
library(knitr)
library(kableExtra)

dt <- mtcars[1:5, 1:6]

kable(dt, format = "rmarkdown")

```

这实际上输出了一个表，但我也在控制台中得到了以下内容:

this actually outputs a table but I also get the following in the console:

    Error in kable_rmarkdown(x = c("Mazda RX4", "Mazda RX4 Wag", "Datsun 710",  : 
  could not find function "kable_rmarkdown"

当我切换到:

```{r}
library(knitr)
library(kableExtra)

dt <- mtcars[1:5, 1:6]

kable(dt, format = "latex")

```

我没有错误，也没有表格.我需要安装乳胶才能使用此功能吗?

I get no error and no table. Do I need to install latex to use this functionality?

推荐答案

只需将注释放在一起即可提供完整的答案:以下引文来自

Just to put the comments together for providing a complete answer: The following quote is from the kableExtra vignette:

从kableExtra 0.9.0开始，加载此程序包(库(kableExtra))时，它将根据您当前的环境自动设置全局选项"knitr.table.format".除非您要渲染PDF，否则kableExtra会尝试为您渲染HTML表.您不再需要在每个kable()函数中手动设置全局选项或格式选项.

Starting from kableExtra 0.9.0, when you load this package (library(kableExtra)), it will automatically set up the global option ’knitr.table.format’ based on your current environment. Unless you are rendering a PDF, kableExtra will try to render a HTML table for you. You no longer need to manually set either the global option or the format option in each kable() function.

因此您可以在两个示例(markdown和LaTeX)中编写:

So you can write in both your examples (markdown and LaTeX):

library(knitr)
library(kableExtra)

dt <- mtcars[1:5, 1:6]

kable(dt)

根据您的输出格式，您将获得以HTML或LaTeX(PDF)呈现的表格.是的:对于PDF，您将需要安装LaTeX.如今，使用 Xihui Xie的TinyTeX 可以很容易地做到这一点.

Depending on your output format you will get the table rendered in HTML or LaTeX (PDF). And yes: For PDF you will need a LaTeX installation. But this is nowadays quite easy with TinyTeX by Yihui Xie.
