我正在尝试编写一个简单的 R 序列聚类/分组/简化解决方案。我是一个初学者，有一段时间没有使用 R，所以请原谅简单和愚蠢的问题/解决方案。任务取自 SAP，它们代表 P2P 流程的执行。
概述：
输入：经过一些建议，我认为输入数据应该涵盖单词而不是它们的 id（我们不想比较数字而是简化单词序列）
选项 1：SAP P2P 中的步骤序列，例如：
Sequence 1:Purchase Order/NB > Goods Receipt/TA > Invoice Receipt/NA > Goods Receipt/TA
Sequence 2:Purchase Order/NB > Goods Receipt/TA > Invoice Receipt/NA
我的数据集包含大约 700 个序列（测试 100），它们既短（5 步）又长（甚至超过 50）。
问题是我（在结果解释期间）不想比较所有，即 700 个序列，但我想以某种方式区分相似的序列。通常，特别是对于长序列，在 20 步之后会发现差异，例如：
Seq1: PR > PO > GR > IR > GR > IR > GR > IR > 付款
Seq2: PR > PO > GR > IR > IR > GR > GR > IR > 付款
最后，它应该会导致发现流程执行中的低效率。我的问题是，你对我如何接近那个问题之王有什么建议吗？阅读您的评论后，我认为聚类方法不是正确的方法。我真的不在乎我们是否应该使用集群或其他东西，重要的是简化流程。
我将不胜感激任何提示，建议等。
