Extract Year from a Vector
In this method, the as.POSIXct is a Date-time Conversion Functions that is used to manipulate objects of classes. To extract the year from vector we need to create a vector with some dates and then arrange the date with as.POSIXct() and get year with format() methods.
R
Date <- c("01/12/2011 12:40:00", "11/12/2015 11:40:00", "01/02/2012 05:40:00", "01/04/2021 09:44:00" , "01/02/2020 01:43:00", "01/12/2014 04:41:00")print("Vector Date:")print(Date)# formatted dateprint("Extract Year:")Date <- as.POSIXct(Date, format = "%m/%d/%Y %H:%M:%S")format(Date, format="%Y") |
Output:
[1] "Vector Date:" [1] "01/12/2011 12:40:00" "11/12/2015 11:40:00" "01/02/2012 05:40:00" [4] "01/04/2021 09:44:00" "01/02/2020 01:43:00" "01/12/2014 04:41:00" [1] "Extract Year:" '2011' '2015' '2012' '2021' '2020' '2014'
