xtable 中的 R Markdown 脚注 [英] R Markdown Footnote in xtable

问题描述

我的 R Markdown 报告中的表格下方没有出现脚注的问题.下面是我用来处理的代码，该代码成功执行，但表格下方没有出现脚注.

I'm having issues with a footnote not appearing under a table in my R Markdown report. Below is the code I'm using to process which does successfully but with no footnote appearing under the table.

```{r ccxtable7, results="asis", echo=FALSE}
comment <- list(pos = list(0), command = NULL)
comment$pos[[1]] <- c(nrow(indPctChgCC))
comment$command <- c(paste("\\hline\n",
                          "{\\footnotesize Note: * signifies number of 
properties used was 35 or less.}\n", sep = ""))

print(xtable(valPctCon(indPctChgCC, indfreqCC, 35), align = "crrrrr", 
             label = "tab:indCC", add.to.row = comment, hline.after = c(-1,0),
caption = "Industrial Certified-Certified Percentage Change per Value Segment"))
```

indPctChCC 是一个 3x5 的字符串矩阵.有人能帮我理解为什么脚注没有出现在带有当前代码的表格下方吗?

indPctChCC is a 3x5 matrix of strings. Could someone help me understand why the footnote is not appearing under the table with this current code?

推荐答案

add.to.row(还有 hline.after)是 的参数打印函数，而不是xtable().

add.to.row (and also hline.after) are arguments of the print function, not xtable().

这应该可以让你到达你想要的地方:

This should get you where you want:

print(xtable(tab, align = "crrr", 
             label = "tab:indCC",
             caption = "Industrial Certified-Certified Percentage Change per Value Segment"), 
      add.to.row = comment, 
      hline.after = c(-1,0))
