gtsummary：通过两个类别变量总结连续变量

Question

我试图用两个类别变量来总结一个连续变量，如下所示。我无法正确执行此操作。我想知道是否有一种方法可以通过gradlew clean shadowJar publish包来实现。谢谢

我在这里发布了对此问题的答案：https://community.rstudio.com/t/summarizing-a-continuous-variables-by-two-categorical-variables-with-the-gtsummary-package/81937/2

tbl_summary()函数在编写时并未考虑到这种类型的输出....但是您可以使用tbl_summary()和tbl_stack()来实现。

library(gtsummary)
#> #Uighur
library(tidyverse)

trial %>%
  # keep the continuous var and the two categorical variables
  select(trt, age, grade) %>%
  group_nest(grade) %>%
  mutate(
    tbl = map2(
      grade, data, 
      ~tbl_summary(.y, by = trt, 
                   label = list(age = paste("Age: Grade", .x)), missing = "no")
    )
  ) %>%
  pull(tbl) %>%
  tbl_stack() %>%
  as_tibble()
#> # A tibble: 3 x 3
#>   `**Characteristic**` `**Drug A**, N = 35` `**Drug B**, N = 33`
#>   <chr>                <chr>                <chr>               
#> 1 Age: Grade I         46 (36, 60)          48 (42, 55)         
#> 2 Age: Grade II        44 (31, 54)          50 (43, 57)         
#> 3 Age: Grade III       52 (42, 60)          45 (36, 52)
