在表实体框架中查找最常用的属性值

Question

我有一个表，每行都有一个名为example2 <- example[, 1, drop = FALSE] # reason_code # 1 d_01, d_03 # 2 d_01 # 3 d_02 # 4 d_02, d_03 library(dplyr) library(tidyr) example3 <- example2 %>% mutate(ID = 1:n()) example4 <- example3 %>% left_join(example3 %>% separate_rows(reason_code, sep = ", ") %>% mutate(Flag = TRUE) %>% spread(reason_code, Flag, fill = FALSE), by = "ID") %>% select(-ID) example4 # reason_code d_01 d_02 d_03 # 1 d_01, d_03 TRUE FALSE TRUE # 2 d_01 TRUE FALSE FALSE # 3 d_02 FALSE TRUE FALSE # 4 d_02, d_03 FALSE TRUE TRUE 的属性，我需要找到表中主要使用的CompanyId。

示例：

CompanyId

如何在表格中找到23？

[id = 1 , CompanyID = 23]
[id = 2 , CompanyID = 10]
[id = 3 , CompanyID = 10]
[id = 4 , CompanyID = 11]
[id = 5 , CompanyID = 23]
[id = 6 , CompanyID = 23]
[id = 7 , CompanyID = 23]
