Question

已经有一段时间了，我遇到了以下问题，慢慢地我变得绝望，因为我无法找到问题的解决方案。我面临以下问题：

使用Stargazer生成HTML回归结果表时，注释部分显示了重要性截止值，如下所示：

*p**p***p<0.01

但是，我更喜欢类似于以下的布局：

Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’

我希望通过动态提取截止值并结合固定的字符向量来实现此目的。 Stargazer手册说：

> a character vector containing notes to be included below the table.
> The character strings can include special substrings that will be
> replaced by the corresponding cutoffs for statistical significance
> 'stars': [*], [**], and [***] will be replaced by the cutoffs, in
> percentage terms, for one, two and three 'stars,' respectively (e.g.,
> 10, 5, and 1). Similarly, [0.*], [0.**] and [0.***] will be replaced
> by the numeric value of cutoffs for one, two and three 'stars' (e.g.,
> 0.1, 0.05, and 0.01). [.*], [.**] and [.***] will omit the leading zeros (e.g., .1, .05, .01).

我现在尝试了所有可能的组合，但我总是失败。我总是以R输出，例如，在HTML文件中输出[***]或者输出错误。

你能帮我找出合适的代码，将笔记中的固定字符串值与动态截止值结合起来吗？

Answer 1

这是一个有趣的问题。在检查代码之后，我认为问题出现是因为使用适当的截止值替换[***]，[**]等的代码来自之前自定义notes向量是应用（当它应该到来之后）。因此，解决方案是重新安排代码，使其按正确的顺序排列。这需要一些代码手术。以下为我工作;我正在运行stargazer_5.2：

library(stargazer)

## Create new stargazer.wrap() to rearrange order of blocks
x <- capture.output(stargazer:::.stargazer.wrap)
idx <- c(grep("for \\(i in 1:length\\(\\.format\\.cutoffs\\)\\)", x)[2],
  grep("if \\(!is\\.null\\(notes\\)\\)", x),
  grep("if \\(!is\\.null\\(notes\\.align\\)\\)", x)[2])
eval(parse(text = paste0("stargazer.wrap <- ", paste(x[c(1:(idx[1] - 1), 
    (idx[2]):(idx[3] - 1), 
    idx[1]:(idx[2] - 1), 
    idx[3]:(length(x) - 1))], collapse = "\n"))))

## Create a new stargazer.() that uses our modified stargazer.wrap() function
x <- capture.output(stargazer)
x <- gsub(".stargazer.wrap", "stargazer.wrap", x)
eval(parse(text = paste0("stargazer. <- ", paste(x[-length(x)], collapse = "\n"))))

结果：首先，之前：

stargazer(lm(mpg ~ wt, mtcars), 
  type = "text",
  notes.append = FALSE,
  notes =  c("Signif. codes: 0 $***$ [.***] $**$ [.**] $*$ [.*]"))

#                                         mpg                    
# ---------------------------------------------------------------
# wt                                   -5.344***                 
#                                       (0.559)                  

# Constant                             37.285***                 
#                                       (1.878)                  

# ---------------------------------------------------------------

正如你所指出的那样，我们遇到了问题。现在，使用我们修改后的stargazer.()函数（注意末尾的点）：

stargazer.(lm(mpg ~ wt, mtcars), 
  type = "text",
  notes.append = FALSE,
  notes =  c("Signif. codes: 0 $***$ [.***] $**$ [.**] $*$ [.*]"))
# ========================================================
#                             Dependent variable:         
#                     ------------------------------------
#                                     mpg                 
# --------------------------------------------------------
# wt                               -5.344***              
#                                   (0.559)               

# Constant                         37.285***              
#                                   (1.878)               

# --------------------------------------------------------
# Observations                         32

# Residual Std. Error           3.046 (df = 30)           
# F Statistic                91.375*** (df = 1; 30)
