R gt软件包:乳胶错误(“此处无行可结束") [英] R gt package: error in latex ("there's no line here to end")
问题描述
我正在尝试在tex文件中包含使用gt()函数生成的表.我创建一个.Rnw文件,然后使用knitr进行编织,并使用pdflatex进行编译.在编译过程中,我收到一个错误:这里没有行结束",这是由表头中的gt()插入换行符引起的.这是MWE:
I am trying to include a table generated with the gt() function in a tex file. I create a .Rnw file, then weave it with knitr and compile with pdflatex. During compilation I get an error: "there no line here to end", caused by a newline inserted by gt() in the table header. This is a MWE:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{booktabs}
\usepackage{longtable}
\usepackage{caption}
\begin{document}
<<setup, include=FALSE>>=
library(knitr)
library(tidyverse)
library(gt)
opts_chunk$set(echo=FALSE)
@
This is a dataframe formatted with the \texttt{gt} package.
<<>>=
tibble(
group=rep(c("A", "B"), each=5),
age = c(20, 24, 22, 27, 29, 21, 24, 23, 30, 31)) %>%
gt %>%
tab_header(title="Some title")
@
\end{document}
tex文件中的结果表为:
The resulting table in the tex file is:
\begin{longtable}{lr}
\caption*{
\large Some title\\
\small \\ % This newline causes the error
} \\
\toprule
group & age \\
\midrule
A & 20 \\
A & 24 \\
A & 22 \\
A & 27 \\
A & 29 \\
B & 21 \\
B & 24 \\
B & 23 \\
B & 30 \\
B & 31 \\
\bottomrule
\end{longtable}
(我在编织后手动添加了评论)
(I added the comment manually after weaving)
由于标题中的换行符(\\
),我得到:./mwe.tex:69: LaTeX Error: There's no line here to end
.如果没有该换行符,则将按预期方式创建PDF.有没有一种方法可以解决此问题而无需手动编辑tex文件?
Because of the newline (\\
) in the caption I get: ./mwe.tex:69: LaTeX Error: There's no line here to end
. Without that newline, the PDF is created as expected. Is there a way to fix this without having to manually edit the tex file?
推荐答案
我发现,当未定义字幕时,这是gt发生的错误. 解决方法是 1)添加一个空格作为字幕,或者
I found that it is a bug of gt happening when there is no subtitle is defined. The work around is 1) adding a space as a subtitle, or
tab_header(title = md("Data listing from **gtcars**"), subtitle = md(" "))
2)手动编辑tex文件
删除登录表中的\small \\
.
2) manually edit the tex file
removing \small \\
in the logntable.
