我有一个日期和时间向量
tm <- c("20231130 162900", "20231009 75400", "20240216 3100", "20230725 0")
我将其转换为时间格式
library(tidyverse)
strsplit(tm, " ") |>
map_chr(\(x) paste(x[1], stringr::str_pad(x[2], 6, "left", "0"))) |>
lubridate::ymd_hms()
结果
[1] "2023-11-30 16:29:00 UTC" "2023-10-09 07:54:00 UTC" "2024-02-16 00:31:00 UTC" "2023-07-25 00:00:00 UTC"
有哪些更短、更易读的选项来进行此转换?
不确定可读性,但您可以将填充操作作为函数传递给
str_replace()
并跳过分割和映射:
library(stringr)
library(lubridate)
#>
#> Attaching package: 'lubridate'
#> The following objects are masked from 'package:base':
#>
#> date, intersect, setdiff, union
tm <- c("20231130 162900", "20231009 75400", "20240216 3100", "20230725 0")
tm |>
str_replace("\\d+$", \(time_) str_pad(time_, 6, "left", "0")) |>
ymd_hms()
#> [1] "2023-11-30 16:29:00 UTC" "2023-10-09 07:54:00 UTC"
#> [3] "2024-02-16 00:31:00 UTC" "2023-07-25 00:00:00 UTC"
