这是一篇更新的帖子，更好地描述了实际数据，并且还包含了John的早期评论。再次感谢他。
我还通过dput（）
直接提供数据我在R中有两个独立的数据框。感兴趣的变量是格式化为序列号的日期，因为我认为它们在数字格式中更容易一些。虽然注意它们不是整数，但它们是长小数，以保持准确性并减少相同值的重复。第一个数据集只是一个DateTime数字的向量。

请注意，'one'中的序列DateTime比'two'中的序列更多。
当对象'one'中的单个序列DateTime位于对象'two'的Start和End serial DateTime之间时，我试图将'two'的ClstrID添加到'one'。换句话说，每个序列的DateTime'一个'如果在开始和结束间隔之间，应该具有'两个'的ClstrID。但请注意，并非所有单个DateTime数字都在开始和结束编号范围内 - 许多单个数字将超出时间间隔。
“一个”的几个日期时间将分为两个不同的时间间隔。 “ 我的实际数据集要长得多，因此我试图将其构建为for（）循环或函数（），以检查“一个”序列号是否在“开始”和“结束”间隔的任何（即所有行）之间。两个'如果是，则将相应的ClstrID添加到'one。'中的相应序列号。
在我之前的帖子中使用John的建议中的代码，我可以从'one'中识别出两个序列号'two'之间的单个序列DateTime。
clstrID.ch <- as.character(two$ClstrID) #Make clstr ID a charater
f <- function(x){
a <- clstrID.ch[ (two$StartTime <= x) & (x <= two$EndTime) ]
if (length(a) == 0) NA else a
}
one$NewID <- lapply(one$DateTimeNumber, f)
但是当我在下面的代码中使用cut()函数时，不断收到有关我中断的唯一性的错误消息 -
cut(one$DateTimeNumber, breaks = c(2, two$EndTime),
labels = two$ClstrID, include.lowest = TRUE, right = TRUE)
错误是......
cut.default出错（一个$ DateTimeNumber，breaks = c（2，两个$ EndTime），labels =两个$ ClstrID，
'休息'不是唯一的
显然我建议我重复DateTime序列号。
任何建议都会受到赞赏和帮助。
感谢。

您不应将重复值传递给breaks=的{{1}}参数。在这种情况下，有10 ...
cut我们来看看：
length(two$EndTime)
# [1] 174
length(unique(two$EndTime))
# [1] 164
所以，那些是重复的价值观。向量已排序，因此每个向量的第一个实例显示在...
badrows <- which(duplicated(two$EndTime))
# [1] 10 34 36 49 50 51 53 101 112 172
two$EndTime[badrows]
# some values
badrows - 1
