如何使用R语言的tidyr包将小时分和秒与数据分开？

Question

Here is the data i had

  temp           time_hour
1 37.04      2013-01-01 05:30:00
2 37.04      2013-01-01 06:30:00
3 37.94      2013-01-01 07:30:00
4 37.94      2013-01-01 08:30:00
5 37.94      2013-01-01 09:30:00

Now i need to separate the time_hour column to "date","month","year" and also to "Hours","minutes","seconds" using tidyr package in R programming languages. I used separate variables to separate date, month, year . i don't know how to separate time like hours, minutes, seconds . Thanks in advance...

Answer 1

We can use separate

library(tidyr)
df1 %>%
    separate(time_hour, into = c("year", "month", "day", "hour", "minutes", "seconds"))
#   temp year month day hour minutes seconds
#1 37.04 2013    01  01   05      30      00
#2 37.04 2013    01  01   06      30      00
#3 37.94 2013    01  01   07      30      00
#4 37.94 2013    01  01   08      30      00
#5 37.94 2013    01  01   09      30      00
