"lubridate" 和 "hms" 包允许提取日期和时间。
一个示例：
date_time_text <- c("2023-04-28 18:04:02")
date_time <- lubridate::ymd_hms(date_time_text)
date <- as.Date(date_time)
time <- hms::as_hms(date_time)
英文:
The lubridate and hms packages allow extraction of dates and times.
An example:
date_time_text <- c("2023-04-28 18:04:02")
date_time <- lubridate::ymd_hms(date_time_text)
date <- as.Date(date_time)
time <- hms::as_hms(date_time)
