问题描述
限时送ChatGPT账号..我想为 POSIXct 对象添加特定的日期.我尝试了以下方法
I would like to add specific days to POSIXct object. I tried the below method
library(lubridate)
input_time = as.POSIXct("2018-05-05T14:14:05")
input_time + lubridate::days(1)
这使输出为2018-05-06 UTC";没有小时和秒 (14:14:05).我希望它的格式与 input_time (2018-05-06T14:14:05) 的格式相同.如何保留小时和秒信息
This gives the output as "2018-05-06 UTC" without the hours and seconds (14:14:05). I would like to have it in the same format as input_time (2018-05-06T14:14:05). How to retain the hours and seconds information
推荐答案
as.POSIXct
未测试您的时间格式.这就是你得到这个结果的原因.
Your time format is not being tested by as.POSIXct
. This is why you get this result.
您可以使用以下格式来使其正确:
You can use the following format to get it correct:
library(lubridate)
# note the format option to get it correct
input_time = as.POSIXct("2018-05-05T14:14:05", format = "%Y-%m-%dT%H:%M:%OS")
input_time + lubridate::days(1)
[1] "2018-05-06 14:14:05 UTC"
或者只是使用 lubridate 的所有函数:
or just use everything with functions from lubridate:
input_time <- lubridate::ymd_hms("2018-05-05T14:14:05")
input_time + lubridate::days(1)
[1] "2018-05-06 14:14:05 UTC"
