Rable不会在Markdown文档中打印

Question

我最近尝试将kable包用于表，尽管我对R脚本获得的结果感到非常满意，但我不知道如何在R Markdown文件中使用它们。 / p>

这是一个可以在R脚本中工作的表的简短示例，但是当我尝试在Markdown文档中重现该表时却不会。

data(mtcars)

mtcars

## @knitr install

check_and_install <- function( packname ) { # given package name, check installation, install if not found
  if ( packname %in% rownames(installed.packages()) == FALSE ) {
install.packages( packname, repos="http://cran.rstudio.com/"  )
  }
}

check_and_install("kableExtra")
check_and_install("dplyr")
check_and_install("qwraps2")
check_and_install("reprex")

library(kableExtra)
library(dplyr)
library(qwraps2)
library(reprex)

## Tableau

summary_test  <-
  list("Cylindres" =
     list("Huit" = ~ qwraps2::n_perc0(cyl == 8,show_symbol=TRUE),
          "Six" = ~ qwraps2::n_perc0(cyl == 6,show_symbol=TRUE),
          "Quatre"  = ~ qwraps2::n_perc0(cyl == 4,show_symbol=TRUE)),
   "Vitesses" =
     list("Cinq" = ~ qwraps2::n_perc0(gear == 5,show_symbol=TRUE),
          "Quatre" = ~ qwraps2::n_perc0(gear == 4,show_symbol=TRUE),
          "Trois" = ~ qwraps2::n_perc0(gear == 3,show_symbol=TRUE))
  )



tabtest2<-summary_table(dplyr::group_by(mtcars, am), summary_test)


kable_out <- kable(tabtest2, format = "html", caption = "",     col.names=c("Auto","Manuelle"), booktabs = T, full_width = F) %>%
  kable_styling(bootstrap_options = c("striped", "hover")) %>%
  kableExtra::group_rows("Cylindres", 1, 3) %>%
  kableExtra::group_rows("Vitesses", 4, 6) 

kable_out

现在，关于下一步，我想将此标签包含在R-markdown文档中，理想情况下，输出将是word文件。这就是我遇到的问题：我找不到合适的方法来包含它。 Markdown完全弄乱了单词输出中的格式。请注意，如果我将输出切换为HTML，就没有问题了。不幸的是，我现在必须提供一个Word文档，所以这不是一个选择。

  kableExtra::group_rows("Cylindres", 1, 3) %>%
  kableExtra::group_rows("Vitesses", 4, 6) 


kable_out
```

创建文档时完全没有问题，一切似乎都顺利运行...

我已经研究了一段时间，但我根本不知道出了什么问题。有谁带领某人？

预先感谢

感谢所做的编辑，使示例可以重现@Mathieu-

所以我看到的几件事正在发生。

1. 您正在输出到Word，但想使用html功能。 Word并非设计用于具有HTML功能（例如“悬停”，“条纹”等）。
2. 您正尝试从另一个表创建者kable的表创建者summary_table创建一个表。如果您查看summary_table，它实际上会创建一个LaTeX标记表。因此，从一种表格形式转换为另一种表格形式将存在问题。

我对其进行了测试，共有三个选项：

创建word文档，但使用qwarps2创建表

knitr::opts_chunk$set(cache = FALSE, include = FALSE)
library(knitr)
opts_chunk$set(echo = FALSE, cache=FALSE)
read_chunk("Test SO.R")
options(qwraps2_markup = "markdown") # this is new
```


```{r install, include=FALSE}
```

## Analyse comparative

```{r table1, include=TRUE, results='asis'}
tabtest2
```

不做任何更改并输出HTML文档

  kableExtra::group_rows("Cylindres", 1, 3) %>%
  kableExtra::group_rows("Vitesses", 4, 6)
```

尝试其他方法，不要使用qwarps2

为什么不直接从数据中直接创建knitr表？即不使用qwraps2？要获得与qwarps2类似的功能，请尝试使用carpenter软件包（免责声明，我创建了它，但是如果不起作用，则在README /第一页的末尾有一个类似软件包的列表）。您可以按照表的方式获取数据，最后使用knitr从混乱的数据创建表。

Answer 2

请考虑以下.Rmd文件以获取示例用例和说明。

---
title: "summary table"
output: rmarkdown::word_document
---

To get the summary table from the
`r  qwraps2::CRANpkg(qwraps2) `
package to render in a word document you need to *not* pass the return from
`r  qwraps2::backtick(summary_test) `
to
`r  paste0(qwraps2::backtick(knitr::kabel), ".") `

The reason is that
`r  qwraps2::backtick(summary_test) `
returns a character matrix and a
`r  qwraps2::backtick(print) `
method is reasponsible for generating either the markdown or LaTeX table.


```{r label = "install_cran", include = FALSE}
# remotes::install_cran is similar to your check_and_install function.
remotes::install_cran("kableExtra")
remotes::install_cran("dplyr")
remotes::install_cran("qwraps2")

```
```{r label = "namespaces"}
library(kableExtra)
library(qwraps2)
```


By default
`r  qwraps2::CRANpkg(qwraps2) `
will format results for LaTeX.  Set the default markup language to markdown
to change this behavior.

```{r }
options(qwraps2_markup = "markdown")
```

**EDIT:** as of version qwraps2 version 0.5.0 the use of the data pronoun
`.data` is no longer needed nor recommented.

```{r label = "define_summary_test"}
summary_test  <-
  list("Cylindres" =
     list("Huit"   = ~ qwraps2::n_perc0(cyl == 8, show_symbol = TRUE),
          "Six"    = ~ qwraps2::n_perc0(cyl == 6, show_symbol = TRUE),
          "Quatre" = ~ qwraps2::n_perc0(cyl == 4, show_symbol = TRUE)),
   "Vitesses" =
     list("Cinq"   = ~ qwraps2::n_perc0(gear == 5, show_symbol = TRUE),
          "Quatre" = ~ qwraps2::n_perc0(gear == 4, show_symbol = TRUE),
          "Trois"  = ~ qwraps2::n_perc0(gear == 3, show_symbol = TRUE))
  )
```


Finally, build the table and look at the structure of the object.


```{r label = 'tabtest2'}
tabtest2 <- summary_table(mtcars, summary_test, by = "am")
str(tabtest2)
```


Note that the object is a
`r  qwraps2::backtick(qwraps2_summary_table)  `
is a character matrix with attributes for the row, column, and row group
names.  Using the default print method in R we see a character matrix.

```{r }
print.default(tabtest2)
```


Using the print method for
`r  qwraps2::backtick(qwraps2_summary_table)  `
objects (done impliclity here) gives the markdown:

```{r results = "markup"}
tabtest2
```


To get the table to render nicely use the "asis" value for the results chunk
option:

```{r results = "asis"}
tabtest2
```
