Rmarkdown无法识别kable_styling命令中的内联

Question

当我运行编织来编译kable_styling或Html时，我的Rmarkdown不能识别_。

我已经按照Yuhui的建议更新了包(包括tinytex和pandoc)，并尝试编译成不同的R版本(3.6.3和4.0.4 - 64位)。

此外，我尝试安装ghostcript包，但没有找到与我的R版本匹配的版本。

这是来自错误的消息

I was unable to find any missing LaTeX packages from the error log projeto1v2.log.

Try to find the following text in projeto1v2.Rmd:
  kable_ 

You may need to add $ $ around a certain inline R expression ´r ´ in projeto1v2.Rmd (see the above
hint). See https://github.com/rstudio/rmarkdown/issues/385 for more info.
Erro: LaTeX failed to compile projeto1v2.tex. See https://yihui.org/tinytex/r/#debugging for
debugging tips. See projeto1v2.log for more info.
Além disso: Warning message:

一个可重复的例子：

library(kableExtra)
winelist <- data.frame(dados[1:12])

sumario <- round(sapply(dados, summary),2)
sumario <- t(sumario)

tabela1 <- data.frame(histograma="", sumario)

tabela1 %>%
kable(booktabs = TRUE) %>%
kable_styling(full_width = FALSE,latex_options = "hold_position", 
row_label_position='c', 
position='center') %>%
kable_paper(full_width = FALSE) %>%
column_spec(4, image = spec_hist(winelist))

有人知道怎么纠正这个错误吗？

Answer 1

你的代码对我来说工作得很好。刚刚将column_spec更改为2：

---
title: "Wine"
output: pdf_document
---

```{r setup, include=FALSE}

knitr::opts_chunk$set(echo =假，warning = FALSE，message =假)

```{r tabeladados}

库(Readr)

存档<- read_csv(“winequality_red /winequality-red.csv”)

dados <- winequality_red

库(KableExtra)

酒商<- data.frame(dados1:12)

sumario <- round(sapply(dados，summary),2)

sumario <- t(sumario)

tabela1 <- data.frame(histograma=""，sumario)

tabela1 %>%

kable(booktabs = TRUE) %>%

kable_styling(full_width = FALSE，latex_options = "hold_position"，

            row_label_position='c', 

            position='center') %>%

kable_paper(full_width = FALSE) %>%

column_spec(2，图像=spec_hist(葡萄酒列表))

-output
