从调查对象创建汇总统计的分层表（数据透视表）

Question

我在通过 gtsummary::tbl_svysummary 创建具有子级别（两个分层；嵌套）的汇总表时遇到问题。

我已经使用以下变量创建了对象调查::svydesign：性别、国家、结果、n（加权）。我设法创建了一个表，但是我无法按性别创建一个额外的层。我已经把我想要的表格结构放在下面了。

我什至可以生成单独的表格（通过过滤器嵌套每个国家/地区）并将它们堆叠起来。但是，有21个国家，我想要一个更合理的策略。

请给点建议...

代码

# dataframe
df <- 
  data.frame(
    Country = c("Country 1", "Country 2", "Country 3", 
               "Country 1", "Country 2", "Country 3",
               "Country 1", "Country 2", "Country 3",
               "Country 1", "Country 2", "Country 3"),
    Result = c("A", "B", "C", 
               "B", "C", "A",
               "C", "A", "B",
               "A", "B", "C"),

这是一个让您非常接近您提供的模拟表的示例。您可以使用 as_flex_table() 将输出转换为 flextable，使其更加相似。

library(tidyverse)
library(gtsummary)

df <- 
  tibble(
    Country = c("Country 1", "Country 2", "Country 3", 
                "Country 1", "Country 2", "Country 3",
                "Country 1", "Country 2", "Country 3",
                "Country 1", "Country 2", "Country 3"),
    Result = c("A", "B", "C", 
               "B", "C", "A",
               "C", "A", "B",
               "A", "B", "C"), 
    Gender = c("M", "M", "M",
               "W", "W", "W",
               "M", "M", "M",
               "W", "W", "W"), 
    n = c(583, 607, 1217,
          487, 1100, 820, 
          178, 304, 367,
          223,444,112))

# Create a weighted survey design object
df_survey <- survey::svydesign(~1,
                               data = df,
                               weights = ~n)


df_results <-
  tibble(Country = unique(df_survey$variables$Country)) %>%
  rowwise() %>%
  mutate(
    # subset the design object within each country
    design = df_survey[df_survey$variables$Country %in% Country, ] %>% list(),
    # construct gtsummary table within each stratum
    tbl = 
      design %>%
      tbl_svysummary(by = Result,
                     percent = "row",
                     include = -Country) %>% 
      add_overall(last = TRUE,
                  col_label = "**n(row)**") %>%
      modify_header(label = "",
                    stat_by = "**{level}**") %>%
      modify_footnote(everything() ~ NA) %>%
      italicize_levels() %>%
      italicize_labels() %>%
      list()
  )

# stack tables
tbl <-
  tbl_stack(
    tbls = df_results$tbl,
    group_header = df_results$Country
  )
