在R中，我们如何在kable()表中添加重要星? [英] In R, how can we add significance stars to a kable() table?

问题描述

使用knitr :: kable()函数通过rmarkdown创建.doc表，我们如何在给定数据帧(df.b)(i.e. cutpoints = c(0, .001,.01,.05, .1, 1), symbols = c("^{***}","^{**}","^{*}","^{.}"," "))中添加显着性星符号"，将其存储在另一个数据帧中的值附近(df.a)?

Using knitr::kable() function to create a .doc table through rmarkdown, how could we add "significance stars symbols" from a given data frame (df.b) (i.e. cutpoints = c(0, .001,.01,.05, .1, 1), symbols = c("^{***}","^{**}","^{*}","^{.}"," ")) near the values stored in another data frame (df.a)?

knitr::kable(df.a)

pander::add.significance.stars()会为此目的而工作，其使用方式与

Would pander::add.significance.stars() work on this purpose, in a similar way as used here?

df.a <-  structure(list(X1 = structure(c(3L, 2L, 4L, 1L), .Label = c("-0.29 (-0.54 - 0.01)",

推荐答案

您可以将两个data.frame对象首先转换为matrix，以便能够逐个paste单元格，然后应用某种格式，例如:

You can convert the two data.frame objects to matrix first to be able to paste the cells one by one, then apply some formatting, eg:

> pander(matrix(paste(as.matrix(df.a),
+                     as.matrix(add.significance.stars(df.b))),
+               nrow = nrow(df.a),
+               dimnames = list(1:nrow(df.a), names(df.a))),
+        split.table = Inf, style = 'rmarkdown', justify = 'left')
