I have a problem here. I have imported my data set into R studio. When I wanted to do STL decomposition, the error that came out is "only univariate series are allowed". How I can overcome this problem?

This is my code to convert my data into a time series data.

data<-ts(TS,start=c(1970,1),end=c(1980,12),frequency=12)

When I ran a STL decomposition with this code:

decomp<-stl(data,s.window="periodic")

This error came out:

Error in stl(data, s.window = "periodic") : only univariate series are allowed

    Please provide a [reproducible example](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) with sample input data and the code you ran that generated the error. – MrFlick Dec 06 '14 at 03:48
  • Yes. Code... we need code. Voting to close as unclear in its current form. You should edit to include an example and what you have done so far. – IRTFM Dec 06 '14 at 05:49
  • @MrFlick i have edited my questions to include the commands – Damien90 Dec 06 '14 at 14:12

    ... but still no data :( We have no idea what `TS` looks like. Post `dput(TS)`, or if that's too long `dput(head(TS))`. – Gregor Thomas Dec 06 '14 at 17:55
  • @Gregor i have put in my data. Sorry for the mess. – Damien90 Dec 07 '14 at 02:42
  • Turns out, i just need to edit my code into this： data<-ts(TS[[1]],start=c(1970,1),end=c(1980,12),frequency=12) Now, I can run STL decomposition on my data. Thanks guys! – Damien90 Dec 07 '14 at 06:58
