我正在尝试在由texreg(lm(speed~dist,data=cars),
custom.note=paste("%stars. This regression should be",
"intepreted with strong caution as",
"it is likely plagued by extensive",
"omitted variable bias"))
创建的表格的底部添加一个相当长的注释;我希望这简单地换行,但似乎没有任何内置于函数中的功能。
采取,例如:
\multicolumn{2}{l}{\scriptsize{$^{***}p<0.001$, $^{**}p<0.01$, $^*p<0.05$. This regression should be intepreted with strong caution as it is likely plagued by extensive omitted variable bias}}
在编译时,它会提供如下内容:
格式是残酷的;更好的是更换标准输出:
\multicolumn{2}{l}{\scriptsize{$^{***}p<0.001$, $^{**}p<0.01$, $^*p<0.05$.}} \\
\multicolumn{2}{l}{\scriptsize{This regression should be intepreted with}} \\
\multicolumn{2}{l}{\scriptsize{strong caution as it is likely plagued by}} \\
\multicolumn{2}{l}{\scriptsize{extensive omitted variable bias}}
更易消化的包装:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
var entityMethod = typeof(DbModelBuilder).GetMethod("Entity");
foreach (var assembly in AppDomain.CurrentDomain.GetAssemblies())
{
var entityTypes = assembly
.GetTypes()
.Where(t =>
t.GetCustomAttributes(typeof(PersistentAttribute), inherit: true)
.Any());
foreach (var type in entityTypes)
{
entityMethod.MakeGenericMethod(type)
.Invoke(modelBuilder, new object[] { });
}
}
}
这使得输出更接近我正在寻找的内容:
有没有办法以编程方式执行此操作?

在版本1.37.1(于2020年5月发布)中,texreg
引入了threeparttable
参数,该参数使用了为此目的而设计的threeparttable
LaTeX软件包。
R代码示例:
texreg(lm(speed ~ dist, data = cars),
custom.note = paste("\\item %stars. This regression",
"should be interpreted with strong",
"caution as it is likely plagued by",
"extensive omitted variable bias."),
single.row = TRUE,
threeparttable = TRUE)
输出:
\begin{table}
\begin{center}
\begin{threeparttable}
\begin{tabular}{l c}
\hline
& Model 1 \\
\hline
(Intercept) & $8.28 \; (0.87)^{***}$ \\
dist & $0.17 \; (0.02)^{***}$ \\
\hline
R$^2$ & $0.65$ \\
Adj. R$^2$ & $0.64$ \\
Num. obs. & $50$ \\
\hline
\end{tabular}
\begin{tablenotes}[flushleft]
\scriptsize{\item $^{***}p<0.001$; $^{**}p<0.01$; $^{*}p<0.05$. This regression should be interpreted with strong caution as it is likely plagued by extensive omitted variable bias}
\end{tablenotes}
\end{threeparttable}
\caption{Statistical models}
\label{table:coefficients}
\end{center}
\end{table}
哪个呈现为:
请注意,自定义注释必须以\\item
开头。也可能有多个项目和/或使用项目符号来格式化多个注释,例如列表中的内容:
texreg(lm(speed ~ dist, data = cars),
custom.note = paste("\\item[$\\bullet$] %stars.",
"\\item[$\\bullet$] This regression",
"should be interpreted with strong",
"caution as it is likely plagued by",
"extensive omitted variable bias."),
single.row = TRUE,
threeparttable = TRUE)
格式不完美,因为您无法设置所需的表格宽度;注释仅会调整为相应表格的宽度。但我认为,在实际使用场景中,一次显示多个模型,并且某些系数名称比示例中的名称更长,这应该不是问题。此解决方案还支持longtable
环境,在这种情况下,将使用threeparttablex
软件包。
下面是一个示例,说明如何通过两种模型使它看起来不错:
fit <- lm(speed ~ dist, data = cars)
texreg(list(fit, fit),
custom.note = paste("\\item[\\hspace{-5mm}] %stars.",
"\\item[\\hspace{-5mm}] This regression",
"should be interpreted with strong",
"caution as it is likely plagued by",
"extensive omitted variable bias."),
single.row = TRUE,
threeparttable = TRUE)
这将产生:
\begin{table}
\begin{center}
\begin{threeparttable}
\begin{tabular}{l c c}
\hline
& Model 1 & Model 2 \\
\hline
(Intercept) & $8.28 \; (0.87)^{***}$ & $8.28 \; (0.87)^{***}$ \\
dist & $0.17 \; (0.02)^{***}$ & $0.17 \; (0.02)^{***}$ \\
\hline
R$^2$ & $0.65$ & $0.65$ \\
Adj. R$^2$ & $0.64$ & $0.64$ \\
Num. obs. & $50$ & $50$ \\
\hline
\end{tabular}
\begin{tablenotes}[flushleft]
\scriptsize{\item[\hspace{-5mm}] $^{***}p<0.001$; $^{**}p<0.01$; $^{*}p<0.05$. \item[\hspace{-5mm}] This regression should be interpreted with strong caution as it is likely plagued by extensive omitted variable bias.}
\end{tablenotes}
\end{threeparttable}

到目前为止,我通过添加texreg
参数并更改以下内容来重写custom.note.wrap
函数,从而提出了一种解决方法:
note <- paste0("\\multicolumn{", length(models) + 1,
"}{l}{\\", notesize, "{", custom.note, "}}")
note <- gsub("%stars", snote, note, perl = TRUE)
要:
if (custom.note.wrap){
note<-paste(paste0("\\multicolumn{", length(models) + 1L,"}{l}{\\",notesize,"{",
strwrap(custom.note, width=custom.note.wrap), "}}"),
collapse = " \\ \n")
note <- gsub("%stars", snote, note, perl = TRUE)
}else{
note <- paste0("\\multicolumn{", length(models) + 1L,
"}{l}{\\", notesize, "{", custom.note, "}}")
note <- gsub("%stars", snote, note, perl = TRUE)
}
我们的想法是为每一行(custom.note.wrap
)选择一个最大字符串长度,然后将提供的音符拆分为最多以空格结尾的长度的字符串,最后将所有内容连接成一堆{{ 1}} s与每个拆分子字符串。
这不是最优的,因为multicolumn
(有能力)在给定模型名称的长度等的情况下自动设置texreg
会更好。但我的原始{{1}缺乏能力,所以我不确定如何做到这一点。

我可能会指出一个整洁的alternative solution I received,您可能会感兴趣,最迟需要更新texreg包时。
因此,自定义注释以LaTeX代码中的\multicolumn
结尾,因此我们无法使用par
或\\
等换行符。但我们可以使用\parbox
实现自动换行。如果我们仍然想要自定义换行符,我们可以使用四个反斜杠\\\\
。为了更好的格式化,我们可以在文本内容的开头使用\\vspace{2pt}
:
texreg(lm(speed ~ dist, data = cars),
custom.note = ("\\parbox{.4\\linewidth}{\\vspace{2pt}%stars. \\\\
This regression should be intepreted with strong caution as it is
likely plagued by extensive omitted variable bias.}"))
