R中的每小时日期序列
问题描述：
我正在尝试每隔一小时生成一系列日期.例如，我尝试了以下操作:
I am trying to produce a sequence of dates at hourly intervals. As an example I tried the following:
> seq(as.Date("1912-02-24 23:00:00"), as.Date("1912-02-25 08:32:00"), by="hour")
会产生错误，但它在 by= 年、月、日时工作正常.
which produces an error, yet it works fine for by= year, month, day.
seq.POSIXt {base} 的文档指出它应该在小时、秒、分钟等时间内工作，但所有这些都会产生错误.
The documentation for seq.POSIXt {base} states that it should work for hour, sec, min, etc, yet all of these produce an error.
> ?seq.POSIXt
提前致谢.
答
好吧，你自己不给答案 ;-)
Well, don't you give the answer yourself ;-)
关于:
seq(as.POSIXct("1912-02-24 23:00:00"), as.POSIXct("1912-02-25 08:32:00"), by="hour")
(也适用于 as.POSIXlt).
