Generation of missiing values in a time serie...

In thinking about this some more, the trick I discussed is probably not the best way to do it since its possible that in the future zoo will completely disallow illegal zoo objects. I think a better way might be to construct it like this: aggregate(zoo(z.data), round(z.time, 1), tail, 1) where z.data is the matrix and z.time are the times. The variable z, which is an illegal zoo object, would not be created but in terms of z, since that is what I have reproducibly from your post, we have: z.data <- coredata(z) z.time <- time(z)
Thanks for your help. However, I have finally implemented a solution by myself, using a loop that iterates over the original serie. I haven't been able to find a way of using these functions and generating a regular time serie in the way I wanted. Thanks anyway. Alvaro
