How to convert a time series object to a vector in R?
To convert a time series object into a vector, we just need to read that object with as.numeric and store it in some other object or in the same object. For example if we have a time series object x then it can be converted to a vector by using x<-as.numeric(x1). To check the difference between a time series object and a vector in R, we must print them.
Example
x1<-ts(rnorm(10,2,0.12)) x1
Output
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
Example
x1<-as.numeric(x1) x1
Output
[1] 1.951703 1.944470 2.126346 1.945275 2.129368 2.100713 1.992308 2.058306 [9] 2.271858 2.055763
Example
is.vector(x1)
Output
[1] TRUE
Example
x2<-ts(rnorm(80,25,2.25)) x2
Output
Time Series: Start = 1 End = 80 Frequency = 1 [1] 24.45105 23.92942 23.02201 22.23093 24.27239 27.95645 26.34687 26.15606 [9] 24.06356 23.78549 25.12992 27.76245 23.10760 21.62202 21.83581 20.67305 [17] 24.59828 22.31877 24.12288 20.08288 27.02836 23.56667 23.34890 28.04439 [25] 21.32559 25.52859 22.82904 25.08876 27.68131 24.25492 23.52403 21.76799 [33] 24.30723 29.73283 28.21973 22.56300 21.80799 27.93293 27.13120 24.44693 [41] 26.88498 22.12067 26.01575 25.21267 28.24337 25.27242 26.30312 26.04764 [49] 24.32843 21.43456 23.17547 29.02772 26.94025 26.59245 23.83956 21.36977 [57] 28.94171 25.04432 24.26455 30.04485 24.42073 17.29558 29.60838 27.14759 [65] 23.25170 24.17799 26.63077 27.22228 28.94655 27.37721 23.64524 27.57805 [73] 24.35631 27.12630 23.30073 23.07521 24.33536 24.05408 24.72586 27.93678
