Hi    

  I am still having problems with using the stl function, when I read the csv file into R into a file called tkr and use dim(tkr) the result is 132 1 which is fine.    

  When coerce it into a trime series using ts either:        

  tstkr <- ts(t(tkr), deltat=1/12) or    

  tstkr <- ts(c(tkr), deltat=1/12)    

  and use the stl function I get the following error:    

  Error in stl(tstkr) : only univariate series are allowed    

  id just use the tkr file I get the same error..does anyibe have an idea what to do next, here is my data...it's not sensitive so if anyone wants to try then you are very welcome!
