【问题描述】：

我正在尝试在rmarkdown 中写一篇研究论文，其中我正在尝试使用stargazer 包创建一个summary stat 表，但是当我包含参数notes = c("All variables are defined in Appendix A.", "All continuous variables are winsorized at 1% and 99%.", "The pctl(25(75) corresponds to 25% (75%) percentile.") 时它向我显示以下错误在stargazer -

! File ended while scanning use of \multicolumn.
<inserted text> 
                \par 
<*> sample_articles.tex

下面是我的tex文件中针对上述问题的表格部分-

但是，如果我去掉上面的notes 参数，它就可以正常工作。

下面是我在rmarkdown 中的r code，在stargazer 中没有notes 参数 -

sumstat_label <- c(
  "DEGREE", 
  "EIGENVECTOR", 
  "BETWEENNESS", 
  "CLOSENESS", 
  "OVERALLCENTRALITY",
  "LNASSETS",
  "LEVERAGE", 
  "INVREC", 
  "LOSS",
  "ROA", 
  "ZSCORE",
  "MERGER",
  "MTB",
  "FOREIGN",
  "EXTRAORDINARY",
  "SEGMENT",
  "SPECIALIZED",
  "MATERIALWEAKNESS",
  "RESTATEMENT",
  "BIGN",
  "GOINGCONCERN",
  "CALENDARYEAR",
  "LNNONAUDFEES",
  "LNAUDFEES",
  "AUDTURNOVER",
  "RESTRUCTURE",
  "LITIGATE",
  "AGE", 
  "AUDITORTENURE",
  "AUDITLAG", 
  "AUDFEES (ml)",
  "NAUDFEES (ml)")

note_label <- c("All variables are defined in Appendix A.",
                "All continuous variables are winsorized at 1% and 99%.",
                "The pctl(25(75) corresponds to 25% (75%) percentile.")
stargazer(as.data.frame(sum_stat[c(
  "DEGREE", 
  "EIGENVECTOR", 
  "BETWEENNESS", 
  "CLOSENESS", 
  "OVERALLCENTRALITY",
  "LNASSETS",
  "LEVERAGE", 
  "INVREC", 
  "LOSS",
  "ROA", 
  "ZSCORE",
  "MERGER",

  "EXTRAORDINARY",

  "MATERIALWEAKNESS",
  "RESTATEMENT",
  "BIGN",
  "GOINGCONCERN",
  "CALENDARYEAR",
  "LNNONAUDFEES",
  "LNAUDFEES",
  "AUDTURNOVER",
  "RESTRUCTURE",
  "LITIGATE",
  "AGE", 
  "AUDITORTENURE",
  "AUDITLAG", 
  "AUDFEES",
  "NAUDFEES")]),
  summary.stat = c("n", "mean", "sd", "p25", "median", "p75"),
  column.sep.width = "-5pt",
  title= "Summary Stat of Variables", type = "latex",
  digits= 1, 
  header = FALSE,
  notes.align = "l",
  font.size = "small",
  single.row = T,
  no.space = T,
  covariate.labels = sumstat_label
)

有没有人知道如何在表中附加notes 参数和type = latex 中的stargazer。谢谢。

【问题讨论】：

我已经能够解决了。只需更改 notes 参数即可帮助解决问题。我像这样更改 notes 参数 - notes = c("All continuous variables are winsorized at 1 and 99 percent", "All variables are defined in Appendix A", "The Pctl (25 (75) corresponds to 25 and 75 percentile") 。问题在于使用% 符号；我只是把它改成percent这个词。谢谢

【解决方案1】：

问题是笔记中的“%”符号作为特殊字符传递给 Latex。在 Latex 中，'%' 的意思是“在这里开始评论并忽略百分号之后的所有内容。”一种解决方案是将百分比符号替换为单词 percent 或 percentile（如原作者评论中所述）。

但在某些情况下，符号更可取（例如在我们希望保持简短的标签中）。在这些情况下，“转义”百分号通常会解决问题。 Stargazer 通常非常擅长清理或“清理”特殊字符，但在这种情况下并不总是像 note_label 选项那样。一些可能的解决方案：

尝试使用百分比这个词而不是符号 %，看看是否一切都在编织
尝试在\% 中使用反斜杠百分比，它告诉 Latex 将其视为常规字符而不是特殊字符。
R / R Markdown 通常更喜欢使用两个反斜杠（一个用于转义反斜杠，一个用于转义百分比）因此也值得尝试（即\\%），如果其他选项都不起作用
尝试使用Hmisc::latexTranslate() 之类的函数手动清理带有下划线、百分比、^s 等字符的文本字符串。在这里查看更多信息：Function to sanitize strings for LaTeX compilation?
