使用哪个 R 时间/日期类和包? [英] Which R time/date class and package to use?

问题描述

我在 R 中的时间序列接触有限.所以，我想知道从哪个时间/日期类(和相关包)开始最合适.

I have a limited time series exposure in R. So, I wonder which time/date class (and associated package) would be most appropriate to start with.

CRAN 任务视图提供的众多软件包中，到目前为止，我赞成 timeDate，它是面向 S4 的，并且很好地支持与位置相关的特殊性，例如节假日和夏令时.

Among the plethora of packages available at CRAN task view, I so far favor the timeDate, which is a S4 oriented and has nice support for location dependent particularities such as holidays and daylight saving times.

社区显然偏爱 zoo 包.chron 也很流行.

The community apparently favors the zoo package. chron is also popular.
[edit: Here is a list of time/date implementations which lubridate package refers to: POSIXct, POSIXlt, Date, chron, yearmon, yearqtr, zoo, zooreg, timeDate, xts, its, ti, jul, timeSeries, fts. Also lubridate itself has handy time classes duration, period and interval.]

如果有使用多个软件包经验的人能就可用时间/日期类在可用性和可扩展性方面的比较发表意见，我将不胜感激.

Would really appreciate if somebody with experience with multiple packages would share his opinion on how the available time/date classes compare in terms of usability and extensibility.

一些兴趣点(按随机顺序):

Some points of interest (in random order):

• 国际化(节假日、时区等)
• 现成的统计建模程序
• 现成的可视化工具
• 易于使用
• 与内置日期/时间序列类 (POSIX,ts) 的兼容性
• 可扩展性(S4 是可取的)
• 最好与 lubridate 一起使用

谢谢.

推荐答案

(应原发帖者的要求，我将把这个从评论移到stackoverflow的答案部分.)

(I am moving this from the comments to the answer portion of stackoverflow at the request of the original poster.)

R News 4/1中有一篇文章(R Help Desk"，第 29 页)专门比较 Date、POSIXct 和 chron.(前两个是 R 的核心，chron 是一个包.)

There is an article in R News 4/1 ("R Help Desk", p. 29) that specifically compares Date, POSIXct and chron. (The 1st two are in core of R and chron is a package.)

timeDate 类(在 timeDate 包中)基于 POSIXct，但具有额外的时区/金融中心支持.

timeDate class (in the timeDate package) is based on POSIXct but has extra time zone/financial center support.

对于规则间隔的系列，tis 包支持许多日期概念.

For regularly spaced series the the tis package supports many notions of dates.

mondate 包支持会计日期.

zoo 时间序列包几乎支持任何日期/时间类，并且还有 yearmon 和 yearqtr 用于 ts 兼容性.

The zoo time series package supports just about any date/time class and also has yearmon and yearqtr for ts compatibility.

xts 时间序列包在 zoo 之上工作，并通过将它们转换为 POSIXct 并返回来处理最常见的日期/时间类再次.

The xts time series package works on top of zoo and handles the most common date/time classes by translating them to POSIXct and back again.

时序 CRAN 任务视图中也有信息.
