包括关于观星者的注释 table 会扭曲列之间的距离

Question

我正在尝试使用 stargazer 包打印一些 table 的 plm 模型。一切正常，直到我尝试向我的 table 添加注释。不幸的是，当我添加注释时，输出 table 失真，每列之间有很大的空格。谁能帮我修一下？提前致谢！

注意：我仍在学习 Latex，因此欢迎提供也适用于 html 的解决方案

#Here I create a simple data.frame just to replicate my data
vector <- rep(0,72)

for (i in 1:72) {
  vector[i] <- rnorm(1)
}

data <- as.data.frame(matrix (vector, nrow = 7))

#This outputs a normal table, with normal space width between columns
stargazer(data,
          type = "text",
          style = "AER")

#This is the note I want to print. However, it returns an error if I space it out like that.
stargazer(data,
          type = "text",
          notes = c("All models were estimated by fixed effects estimator. Errors are robust to heteroscedasticity and 
                    autocovariance. Numbers between parenthesis are the coefficient standard deviations. * represents 
                    significance at the 10 % level, ** represents significance at the 5% level, and *** represents significance 
                    at the 1% level. Models (1), (2) and (3) refer, respectively, to equations (7), (8) and (9)"),
          style = "AER")


#This outputs the table. However, there are big blank spaces between columns. How do I fix this?
stargazer(data,
          type = "text",
          notes = c("All models were estimated by fixed effects estimator. Errors are robust to heteroscedasticity and autocovariance. Numbers between parenthesis are the coefficient standard deviations. * represents significance at the 10 % level, ** represents significance at the 5% level, and *** represents significance at the 1% level.

LaTeX 解决方案

我遇到了类似的问题，这是我针对 LaTeX 的解决方案。

首先，您需要一个单独的函数来创建自己的包含注释的小页面。

library(stargazer)

stargazernote <- function(starGazerCmd, outputfile, note){
  # inserts 'note' to the end of stargazer generated latex table
  ssn <- gsub(x=starGazerCmd, pattern='\end{tabular}',
              replacement=paste('\end{tabular}', '\n',
                                '\centerline{\begin{minipage}{0.95\textwidth}~\', '\n',
                                '\footnotesize{' , note, 
                                '} \end{minipage}}',  sep=''), fixed=T)

  cat(ssn,sep='\n',file=outputfile)
}

（您可能想尝试使用参数 {0.95\textwidth}。有些人喜欢音符的宽度稍宽或稍窄。）

创建你的 stargazer 乳胶 table 不带注释如下：

s <- stargazer(data,
          type = "latex",
          style = "AER",
          notes.append=FALSE,
          )

然后单独创建笔记：

note <- "All models were estimated by fixed effects estimator. Errors are robust to heteroscedasticity and autocovariance. Numbers between parenthesis are the coefficient standard deviations. * represents significance at the 10 \% level, ** represents significance at the 5\% level, and *** represents significance at the 1\% level. Models (1), (2) and (3) refer, respectively, to equations (7), (8) and (9)"

这是第一个陷阱：% 符号被 LaTeX 解释为注释符号，因此您需要通过在 % 前面加上 \ 来转义它们。

现在你可以使用上面的函数来整理笔记和 LaTeX table:

stargazernote(s, note=note, outputfile='foo.tex')

输出如下所示：

第二个问题是您需要记住在 LaTeX 文件中包含 graphicx。 .tex 文件可能如下所示：

\documentclass[english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}

\usepackage{graphicx} %% note: the table will not render without this package. 

\begin{document}
\include{foo.tex}
\end{document}

文字解

您可以像这样强制更改注释中的行（这是从 this SO question 复制的）：

stargazer(data,
          type = "text",
          notes= c("All models were estimated by fixed effects estimator.", 
                    "Errors are robust to heteroscedasticity and autocovariance.", 
                    "Numbers between parenthesis are the coefficient standard deviations.", 
                    "* represents significance at the 10 % level", 
                    "** represents significance at the 5% level,", 
                    "and *** represents significance at the 1% level.", 
                     "Models (1), (2) and (3) refer, respectively, to equations (7), (8) and (9)"),
          style = "AER")

输出：
