Reshape/Transpose 在 R studio 中将行复制到列

Question

我有这样的数据：

ID	Name	Adress	Score	Requirement	Status
1	John	CA	1	Internet	OK
1	John	CA	1	TV	Not OK
1	John	CA	1	Household	OK
2	Ann	LA	3	Internet	Not OK
2	Ann	LA	3	TV	Follow up
...	...	...	...	...	...

每个“客户”的ID都是唯一的，从第1-3行开始，ID、姓名、地址和分数都是相同的。每个客户有 3 个要求，我想将这 3 个要求转换为状态为值的列，以便删除重复项。如下：

ID	Name	Adress	Score	Internet	TV	Household
1	John	CA	1	OK	Not OK	OK
2	Ann	LA	3	Not OK	Follow up	OK
...	...	...	...	...	...	...

我尝试在 R studio 中搜索 reshape 和 dcast 之前的案例，但没有找到与我的相似的案例。有人能帮我吗？非常感谢！

您可以使用 tidyr 包中的pivot_wider

library(dplyr)
library(tidyr)

# your data
df <- tribble(
  ~ID, ~Name, ~Adress, ~Score, ~Requirement, ~Status,
  1, "John", "CA", 1, "Internet", "OK", 
  1, "John", "CA", 1, "TV", "Not OK", 
  1, "John", "CA", 1, "Household", "OK", 
  2, "Ann", "LA", 3, "Internet", "Not OK", 
  2, "Ann", "LA", 3, "TV", "Follow up")


df <- df %>% 
  pivot_wider(names_from = Requirement, values_from = Status)
