`dplyr::full_join()` 不适用于列表列

Question

我正在尝试比较 R 包 ggstatsplot 中给定函数的两个版本的形式。我已经能够在小标题中提取形式，但我似乎无法让这两个表加入。 dplyr::full_join() 会产生一个错误，但并不清楚它的含义。对于如何加入这两个数据框的任何反馈，我们将不胜感激。

# setup
set.seed(123)
library(tidyverse)
library(ggstatsplot)

# formals for the primary version of the function
(df_primary <- tibble::enframe(formals(ggstatsplot::gghistostats)) %>%
  dplyr::rename(.data = ., primary = value))

#> # ... with 31 more rows

# formals for the grouped version of the function
(df_grouped <- tibble::enframe(formals(ggstatsplot::grouped_gghistostats)) %>%
  dplyr::rename(.data = ., grouped = value))
#> # A tibble: 43 x 2

似乎不支持dotted paired 类型。一件事，我们可以将其转换为普通的list，然后执行full_join

formals(ggstatsplot::gghistostats) %>% 
     as.list %>% 
     tibble::enframe(value = 'primary') %>% 
     full_join(formals(ggstatsplot::grouped_gghistostats) %>% 
                 as.list %>% 
                 tibble::enframe(value = 'grouped'))
# A tibble: 40 x 3
#   name        primary   grouped  
#   <chr>       <list>    <list>   
# 1 data        <NULL>    <missing>
# 2 x           <missing> <missing>
# 3 binwidth    <NULL>    <NULL>   
# 4 bar.measure <chr [1]> <chr [1]>
# 5 xlab        <NULL>    <NULL>   
# 6 title       <NULL>    <NULL>   
# 7 subtitle    <NULL>    <NULL>   
# 8 caption     <NULL>    <NULL>   
# 9 type        <chr [1]> <chr [1]>
#10 test.value  <dbl [1]> <dbl [1]>
# … with 30 more rows
