R 如何将datetime转换为POSIXct或将数字/聚合时间序列间隔转换为小时间隔？

我一直在尝试将timeseries数据聚合为1小时timeseries，方法是添加该小时的“径流”

 ##aggregate timeseries by the hour and sum the runoff
 aggregate(LD1['Surface Runoff'], list(cut(LD1$Date, "1 hour")), sum)

我得到了错误：“x”必须是切割中的数字（LD1$Date，“1小时”）

我尝试将日期时间转换为POSIXct，但它一直说我的数据格式不明确，这是有意义的，因为日期不在序列中

我的最终结果与我的非常相似 但我不知道如何继续下去

非常感谢您的帮助

多谢各位

编辑：这是使用dput函数的日期/时间示例
