表 R Markdown qwraps2 和 knitr::kable。 列丢失

Question

我有以下虚拟 data.frame

set.seed(12345)
df<-data.frame(var1=floor(runif(10,1000000,5000000)),  group=rep(c("A","B"),5), event=rep(c("Yes","No"),5))

并想为其创建一个汇总表。 我尝试使用qwraps2

如下：

summary<-list("VAlue1" =
          list("min" = ~ min(.data$var1),
              "max" = ~ max(.data$var1),
              "mean (sd)" = ~ qwraps2::mean_sd(.data$var1)),

       "Group" =
         list("Yes" = ~ qwraps2::n_perc0(.data$group == "A"),
              "No"  = ~ qwraps2::n_perc0(.data$group == "B")))
knitr::kable(
  qwraps2::summary_table(dplyr::group_by(df, event),summary )
)

不幸的是，输出缺少要查看的变量：

|          |event: No (N = 5)                |event: Yes (N = 5)                 |
|:---------|:--------------------------------|:----------------------------------|
|min       |2591303                          |1315253                            |
|max       |4232714                          |4711820                            |
|mean (sd) |3,456,579.40 ± 672,665.35 |3,029,844.00 ± 1,572,709.32 |
|Yes       |0 (0)                            |5 (100)                            |
|No        |5 (100)                          |0 (0)                              |

如何合并类别“Value1”和“Group”？

谢谢！

也欢迎对其他软件包的建议。

Answer 1

summary_table返回的对象是一个带有附加 S3 类qwraps2_summary_table的字符矩阵。 行Group名称Value1和Group不是字符矩阵的一部分，它们是部分属性。 qwraps2_summary_table对象的打印方法根据适当的标记语言、LaTeX 或qwraps2_summary_table需要构建表。

对发布的示例进行两次编辑以获取您要查找的表格：

1. 将options(qwraps2_markup = "markdown")到您的脚本中。 默认标记语言是 LaTeX，设置此选项会将默认值更改为 Markdown。

2. 不要将summary_table包裹在knitr::kable ：这会阻止调用所需的打印方法。

options(qwraps2_markup = "markdown")

set.seed(12345)
df <- data.frame(var1  = floor(runif(10,1000000,5000000)),
                 group = rep(c("A","B"),5),
                 event = rep(c("Yes","No"),5))


summary <- list("Value1" =
                list("min" = ~ min(var1),
                     "max" = ~ max(var1),
                     "mean (sd)" = ~ qwraps2::mean_sd(var1)),
                "Group" =
                  list("Yes" = ~ qwraps2::n_perc0(group == "A"),
                       "No"  = ~ qwraps2::n_perc0(group == "B")))


tab <- qwraps2::summary_table(df, summaries = summary, by = "event")
str(tab)
