我没有成功尝试了以下内容:

I tried the following without sucess:

推荐答案

要保留时间，您应该将其转换为实际的日期时间，从中可以轻松构建一次增加1天的序列.您可以使用 strftime 随意设置其格式.

To preserve times you should convert to actual date-times, from which it is easy to build a sequence increasing by 1 day at a time. You can use strftime to format this as you please.

strftime(seq(as.POSIXct("2020-07-23 10:20"), by = "1 day", length.out = 7), "%b %e %H:%M")
#> [1] "Jul 23 10:20" "Jul 24 10:20" "Jul 25 10:20" "Jul 26 10:20" "Jul 27 10:20"
#> [6] "Jul 28 10:20" "Jul 29 10:20"
