在与同事讨论性能,教学,发送错误报告或在邮件列表上搜索指导时,以及在Stack Overflow上,通常会询问可重复的示例并始终提供帮助.

您有什么建议创建优秀示例的提示？如何以文本格式粘贴r中的数据结构？您还应该包含哪些其他信息？

在另外还有其他招数来使用dput(),dump()或structure()？你什么时候应该包括library()或require()声明？其中保留字应避免一个,此外c,df,data等？

怎样才能成为一位伟大的[R重复的例子？

这看起来应该是常见的事情,但我所有的搜索都会提出一半或未完成的答案.

我在csv中有一组数据.但是数据的设置是时间,价格,数量.为了正确分析我的数据,我需要OHLCV格式:开放,高,低,关闭,音量.

有谁知道如何重新格式化为OHLCV？

以下是数据集的示例:
