是否有办法保证lubridate产生的输出与输入不同？
下面是一个玩具示例，其中我在玩一些旧代码，这些代码会乱码单词中的字母，除了第一个和最后一个。我注意到对于短序列df <- structure(list(WEEK = structure(c(13885, 13885, 13892, 13892,

会“随机地”将字母改回其原始位置并产生不希望的输出。因此，要“解决”该问题，我只需再次运行std::shuffle。
用简单的话来说，有没有一种方法可以避免while循环，或者仅仅是std::shuffle的怪癖？
std::shuffle答案 0 :(得分：-1)
std::shuffle正在按预期工作，并返回给定序列的随机排列。即使与输入相同。
重新滚动不需要的输出上的序列是最简单的解决方案，而且“反洗牌”无论如何都可能完成。
