Hi, 

I have imported a csv file into R which contains one column (the rate er 100,000 population of a disease, by month over 11 years) I coerced into a time series using the following function, 

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

This seems to work fine, and when I check for the class of the object using class(tstkr) I get "ts" as the response. 

When I try to use the stl function in stats I get the error message: 

Error in stl(tstkr)only univariate series are allowed 

I then tried this: 

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

however this made no difference...I still get an error - does anybody know what is wrong? 

Regards, 

Daniel
