如何使用带 R 的正则表达式在文本文件中列出结果列表？
How to make a list of the findings in a text file by using Regular Expression with R?
我必须将文本字符向量中的所有参数转换为易于参考的格式：使用 R 的具有 3 列（演示者、时间和文本）的列表（抱歉，我应该更清楚).
例如，主持人应该是
# HARPER'S
时间应该是
# [Day 1, 9:00 A.M.]
和文本应该是参数中的其余部分。
我需要计算文本中参数的数量（
的每个开始
# HARPER'S [Day 1, 9:00 A.M.]
是一个参数）。我想创建一个名为 'arguments' 的新列表对象，列表中的每个元素都是一个包含三个元素（'presenter'、'time' 和 'text'）的子列表。
然后将演示者姓名和时间提取到两个字符向量中（同时删除缩进），并在该参数的子列表中保留 'presenter' 元素和 'time' 元素。

使用您想要捕获给定文本的方式，此正则表达式应该完成您的工作，因为它将演示者、时间和文本捕获到三组中，并使用 re.findall 找到所有文本并将它们放入一个列表，其中这三个信息中的每一个都作为列表中的单个元素存在于元组中。检查这个正则表达式演示，
