r - 在 R 中，创建一列用引号括起来并用逗号分隔的标签名称

Question

在 R 中，我试图为 tibble 创建一个列，该列将包含一串标签，这些标签将用于在 MailChimp 中分割电子邮件列表。
我将上传到 MailChimp 的输出 CSV 中标签列的格式应该是一个字符串:“属性 1”、“属性 2”
我怀疑这样做将涉及使用 if 语句创建一个函数，并添加一个基于 TRUE/FALSE 逻辑的标记。
下面是数据结构的样子:

library(tidyverse)

person <- c("Person 1", "Person 2", "Person 3", "Person 4")
is_in_A <- c(TRUE, FALSE, TRUE, FALSE)
is_in_B <-  c(TRUE, FALSE, FALSE, TRUE)
is_in_C <- c(TRUE, TRUE, TRUE, TRUE)

example_tbl <- tibble(person = person, is_in_A = is_in_A, is_in_B, is_in_C = is_in_C)

this is what the data looks like:
example_tbl

# person   is_in_A is_in_B is_in_C  
# <chr>     <lgl>   <lgl>   <lgl>   
# Person 1  TRUE    TRUE    TRUE    
# Person 2  FALSE   FALSE   TRUE    
# Person 3  TRUE    FALSE   TRUE    
# Person 4  FALSE   TRUE    TRUE    

输出应该是这样的:

tags_1 <- '"is in A", "is in B", "is in C"'
tags_2 <- '"is in C"'
tags_3 <- '"is in A", "is in C"'
tags_4 <- '"is in B", "is in C"'

all_tags <- c(tags_1, tags_2, tags_3, tags_4)

example_output_tbl <- example_tbl %>%
  add_column(tags = all_tags)

# this is what the output should look like
example_output_tbl

# person   is_in_A is_in_B is_in_C  tags
# <chr>     <lgl>   <lgl>   <lgl>   <chr>
# Person 1  TRUE    TRUE    TRUE    "is in A", "is in B", "is in C"
# Person 2  FALSE   FALSE   TRUE    "is in C"
# Person 3  TRUE    FALSE   TRUE    "is in A", "is in C"
# Person 4  FALSE   TRUE    TRUE    "is in B", "is in C"

欢迎大家提出意见。

这个base R有帮助:

example_tbl$Col <- apply(example_tbl[,-1],1,function(x) paste(names(example_tbl[,-1])[which(x==T)],collapse = ','))

# A tibble: 4 x 5
  person   is_in_A is_in_B is_in_C Col                    
  <chr>    <lgl>   <lgl>   <lgl>   <chr>                  
1 Person 1 TRUE    TRUE    TRUE    is_in_A,is_in_B,is_in_C
2 Person 2 FALSE   FALSE   TRUE    is_in_C                
3 Person 3 TRUE    FALSE   TRUE    is_in_A,is_in_C        
4 Person 4 FALSE   TRUE    TRUE    is_in_B,is_in_C
