如何在R中将时间序列对象转换为向量？
要将时间序列对象转换为向量，我们只需要使用as.numeric读取该对象并将其存储在其他某个对象或同一对象中即可。例如，如果我们有一个时间序列对象x，则可以使用x<-as.numeric(x1)将其转换为向量。要检查时间序列对象和R中的向量之间的差异，我们必须打印它们。
示例
x1<-ts(rnorm(10,2,0.12)) x1
输出结果
Time Series: Start = 1 End = 10 Frequency = 1 [1] 1.951703 1.944470 2.126346 1.945275 2.129368 2.100713 1.992308 2.058306 [9] 2.271858 2.055763
示例
x1<-as.numeric(x1) x1
输出结果
[1] 1.951703 1.944470 2.126346 1.945275 2.129368 2.100713 1.992308 2.058306 [9] 2.271858 2.055763
示例
is.vector(x1)
输出结果
[1] TRUE
示例
x2<-ts(rnorm(80,25,2.25)) x2
