问题描述

基础 R 函数 diff 计算一阶差分，对滞后数据比较有用.

The base R function diff computes a first difference, useful for lagged data comparisons.

我正在寻找可在 R 中访问的 GNU diff 函数:https://www.computerhope.com/unix/udiff.htm

此功能对于版本控制很有用，但在自然语言过程中也很有用，以识别两个相似文本元素之间的更改或编辑.这也是git等的底层引擎.

This function is useful for version control, but also useful in natural language processes to identify changes or edits between two similar text elements. This is also an underlying engine of git and so on.

理想情况下，函数应该是 gnudiff(text1,text2)，如果绑定到 quanteda 或其他库，那就太棒了.

Ideally the function would be gnudiff(text1,text2) and if tied to quanteda or another library, that would be awesome.
