我有几个藏语:
一:
structure(list(contacts = c(151, 2243, 4122, 6833, 76, 123)), .Names = "contacts", row.names = c(NA,
-6L), class = c("tbl_df", "tbl", "data.frame"))
二:
structure(list(image_names = c("/storage/emulated/0/Pictures/1.png",
"/storage/emulated/0/Pictures/10.png", "/storage/emulated/0/Pictures/2.png",
"/storage/emulated/0/Pictures/3.png", "/storage/emulated/0/Pictures/4.png",
"/storage/emulated/0/Pictures/5.png")), .Names = "image_names", row.names = c(NA,
-6L), class = c("tbl_df", "tbl", "data.frame"))
三:
structure(list(phone_number = c(22881, 74049, 74049, 22881, 22881,
22881), isInContact = c(TRUE, TRUE, TRUE, TRUE, TRUE, TRUE),
callDuration = c(1, 0, 0, 71, 13, 54), Date = structure(c(17689,
17689, 17689, 17690, 17690, 17690), class = "Date"), Time = structure(c(76180,
77415, 84620, 27900, 28132, 29396), class = c("hms", "difftime"
), units = "secs")), .Names = c("phone_number", "isInContact",
"callDuration", "Date", "Time"), row.names = c(NA, -6L), class = c("tbl_df",
"tbl", "data.frame"))
考虑一下,对于这些数据帧的每一组,我都可以得到一个标识符,比如uuid。
我想构建一个大型数据帧对象,其中标识符将是用户的uuid,而所有其他列将是嵌套的tibbles:
UUID contacts images call_logs
123 <tibble> <tibble> <tibble>
456 <tibble> <tibble> <tibble>
请告诉我怎样才能建造这样的东西,我正在尝试使用
map_dfr
没有运气。
