Dear All, I am getting the following error when i am using interpNA function from timeSeries package # Missing Value Treatment (Linear Interpolation)
spt = interpNA(spt, method = c("linear"))

It puzzles me why you have not investigated an error message that seems quite informative. When I looked at the code of timeSeries::interpNA I was puzzled that the package seems to use "timeSeries" as the class name. This error reports a different class name, but it does seem that the function is designed to take only a particular set of intputs and yours fails that test.
fut = interpNA(fut, method = c("linear"))
Error in interpNA(fut, method = c("linear")) : fut is not a tis object
spt = ts(spt, start=c(2006,4), frequency=305)
fut = ts(fut, start=c(2006,4), frequency=305)
spt = interpNA(spt, method = c("linear"))
So the lack of an error here suggests that a ts-object might be acceptable to the same function that you were asking about.
