要创建以分钟为单位的日期序列，我们可以使用seq函数，并使用as.POSIXct定义日期和时间。例如，如果我们要生成一个时间序列，该时间序列介于2020年10月10日下午2点到同一日期的下午4点，则可以使用以下代码-
seq(from=as.POSIXct("2020-10-10 14:00"),to=as.POSIXct("2020-10-10 16:00"),by="min")seq(from=as.POSIXct("2020-01-01 00:01"),to=as.POSIXct("2020-01-01 01:00"),by="min")输出结果

我们可以在tz参数的帮助下通过使用不同的时区来创建这些序列，如下所示-
