打印数据框时如何更改观星者中的列名？

Question

我正在尝试使用 stargazer 包在乳胶中输出数据框。我希望列名称包含乳胶代码，但 stargazer 不允许在数据框名称中包含乳胶代码。我也尝试过使用 column.labels 参数，但是这个参数只用于回归表，而不是用于输出数据帧。这是我尝试过的两种方法。都没有用。

第一种方法 - 尝试更改数据框中变量的名称

代码:

# Creating a data frame
df = data.frame(x = 1:5, y = 6:10)

# Changing names
names(df) = c("$X$", "$Y$\textsuperscript{1}")

# Exporting
stargazer(df, summary = F, 
  notes = "\textsuperscript{1} This is a note that was supposed to refer to $Y$.")

输出（显然stargazer不识别LaTeX代码）：

% Table created by stargazer v.5.2 by Marek Hlavac, Harvard University. E-mail: hlavac at fas.harvard.edu
% Date and time: Sat, Oct 29, 2016 - 20:46:22
\begin{table}[!htbp] \centering 
  \caption{} 
  \label{} 
\begin{tabular}{@{\extracolsep{5pt}} ccc} 
\[-1.8ex]\hline 
\hline \[-1.8ex] 
 & $X$ & $Y$\textbackslash textsuperscript\{1\} \ 
\hline \[-1.8ex] 
1 & $ & $ \ 
2 & $ & $ \ 
3 & $ & $ \ 
4 & $ & $ \ 
5 & $ & $ \ 
\hline \[-1.8ex] 
\end{tabular} 
\end{table}

第二种方法——尝试使用column.labels参数

代码:

# Creating a data frame
df = data.frame(x = 1:5, y = 6:10)

# Exporting
stargazer(df, summary = F, 
  column.labels = c("$X$", "$Y$\textsuperscript{1}"),
  notes = "\textsuperscript{1} This is a note that was supposed to refer to $Y$.")

输出（观星者直接忽略参数）：

\hline \[-1.8ex] 
1 & $ & $ \ 
2 & $ & $ \ 
3 & $ & $ \ 
4 & $ & $ \ 
5 & $ & $ \ 
\hline \[-1.8ex] 
\multicolumn{3}{l}{\textsuperscript{1} This is a note that was supposed to refer to $Y$.} \ 
\end{tabular} 
\end{table}

Answer 1

有点 hacky，但这里的主要思想是 gsub 使用我们想要的 Latex 代码输出 stargazer 中的相关行：

# Creating a data frame
df = data.frame(x = 1:5, y = 6:10)

out <- capture.output(
  stargazer(df, summary = F, 
    notes = "\textsuperscript{1} This is a note that was supposed to refer to $Y$.")
)

# Changing names
vars = c("x" = "$X$", "y" = "$Y$\\textsuperscript{1}")
cat(sep = "\n",
  gsub(paste(names(vars), collapse = " & "), paste(vars, collapse = " & "), out)
)
# \begin{table}[!htbp] \centering 
#   \caption{} 
#   \label{} 
# \begin{tabular}{@{\extracolsep{5pt}} ccc} 
# \[-1.8ex]\hline 
# \hline \[-1.8ex] 
#  & $X$ & $Y$\textsuperscript{1} \ 
# \hline \[-1.8ex] 
# 1 & $ & $ \ 
# 2 & $ & $ \ 
# 3 & $ & $ \ 
# 4 & $ & $ \ 
# 5 & $ & $ \ 
# \hline \[-1.8ex] 
# \multicolumn{3}{l}{\textsuperscript{1} This is a note that was supposed to refer to $Y$.} \ 
# \end{tabular} 
# \end{table}

当使用参数 align = T 时，尝试

vars = sprintf("\\multicolumn\{1\}\{c\}\{%s\}", 
  c("$X$", "$Y$\\textsuperscript{1}"))
names(vars) <- sprintf("\\multicolumn\{1\}\{c\}\{%s\}", names(df))
cat(sep = "\n",
  gsub(paste(names(vars), collapse = " & "), paste(vars, collapse = " & "), out)
)

你可以这样做，但是运行设置名称之前的代码，你不想输入不相关的名称，

stargazer(GLM.1$finalModel, GLM.2$finalModel, GLM.3$finalModel,
      out = "my.GLMs.htm",
      title = "Logistic Models", type = "html", 
      single.row = TRUE, report = "vc*", df = FALSE, header = FALSE, digits=2, 
      column.labels = c("GLM 1", "GLM 2", "GLM 3"), apply.coef=exp, 
      p.auto=F, dep.var.caption  = "Odds Ratio", intercept.bottom = FALSE,
      covariate.labels=c( "Gender", "Marital Status","Age", "Employed",  "Education",
                          "Political Affiliation", "Rural", "Ethnicity", "Region", "Gross Income", "Networth","Networth-HomeEquity",  "Liquid Assets"))
