Question

我有以下时间序列：

library(lubridate)
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 = ",")

我想创建z2对象的向量/数组zoo，例如：

z2[1]<-window(z, start = parse_date_time("20/11/2014 15:00", orders = "%d-%m-%Y H!:M!"), 
   end = parse_date_time("20/11/2014 16:00", orders = "%d-%m-%Y H!:M!"))
z2[2]<-window(z, start = parse_date_time("20/11/2014 17:00", orders = "%d-%m-%Y H!:M!"), 
   end = parse_date_time("20/11/2014 23:00", orders = "%d-%m-%Y H!:M!"))
z2[3]<-window(z, start = parse_date_time("21/11/2014 16:00", orders = "%d-%m-%Y H!:M!"), 
   end = parse_date_time("21/11/2014 17:00", orders = "%d-%m-%Y H!:M!"))

所以我将能够使用z2 [1]，z2 [2]和z2 [3]作为每个动物园对象。

感谢@ 42：

z2 <- list()
z2[[1]]<-window(z, start = parse_date_time("20/11/2014 15:00", orders = "%d-%m-%Y H!:M!"), 
   end = parse_date_time("20/11/2014 16:00", orders = "%d-%m-%Y H!:M!"))
z2[[2]]<-window(z, start = parse_date_time("20/11/2014 17:00", orders = "%d-%m-%Y H!:M!"), 
   end = parse_date_time("20/11/2014 23:00", orders = "%d-%m-%Y H!:M!"))
z2[[3]]<-window(z, start = parse_date_time("21/11/2014 16:00", orders = "%d-%m-%Y H!:M!"), 
   end = parse_date_time("21/11/2014 17:00", orders = "%d-%m-%Y H!:M!"))
