Выберите диапазон времени от зоопарка времени серии

Question

У меня есть следующие временные ряды:

library (zoo) 
ts1 <- "f,c 
    1,19/11/2014 12:00,0.01 
    2,19/11/2014 13:00,0.01 
    3,20/11/2014 15:00,0.01 
    4,20/11/2014 16:00,0.01 
    5,20/11/2014 17:00,0.01 
    6,20/11/2014 19:00,0.01 
    7,20/11/2014 22:00,0.20 
    8,20/11/2014 23:00,0.03 
    9,21/11/2014 16:00,0.01 
    10,21/11/2014 17:00,0.01" 

z <- read.zoo(text = ts1, tz = "", format = "%d/%m/%Y %H:%M", sep = ",") 

Я хотел бы создать новый зоопарк - z1, что будет подмножество г, который будет включать в себя диапазон времени 20/11/2014 15:00 до 20/11/2014 23:00. Он будет включать в себя следующее:

3,20/11/2014 15:00,0.01 
    4,20/11/2014 16:00,0.01 
    5,20/11/2014 17:00,0.01 
    6,20/11/2014 19:00,0.01 
    7,20/11/2014 22:00,0.20 
    8,20/11/2014 23:00,0.03 

Answer 1

library(lubridate) 
window(z, start = parse_date_time("20/11/2014 15:00", orders = "%d-%m-%Y H!:M!"), 
    end = parse_date_time("20/11/2014 23:00", orders = "%d-%m-%Y H!:M!"))
