删除检查多行数据帧的重复项

Question

具有数据帧：

dframe <- data.frame(id = c(1,2,3,2,2), name = c("Google","Google","Google","Amazon","Google"))

如何在同一时间检查两列并删除重复的

示例输出

data.frame(id = c(1,3,2,2), name = c("Google","Google","Amazon","Google"))

我尝试了

dframe[!duplicated(dframe ["id", "name"]), ] 

Answer 1

dplyr中的distinct函数可能就是您想要的：

dframe %>%
distinct(id, name)
id   name
1  1 Google
2  2 Google
3  3 Google
4  2 Amazon
