Assume I have the vector c(3,7,1,9,7,6,4) and I need to get its three least elements c(3,1,4). How can I do it with R?
假设我有矢量c(3,7,1,9,7,6,4),我需要得到它的三个最小元素c(3,1,4)。我怎么能用R做呢?

One possible solution:
一种可能的方案:
sort( c(3,7,1,9,7,6,4) )[1:3]

Another possible solution:
另一种可能的方案
sort(x = c(3,7,1,9,7,6,4), partial = 3)[1:3]
Which performs a partial sort.
哪个执行局部排序。
