Usually, problems like this occur when the time stamps in one of your time series are not unique. Maybe we should improve the error message by explicitely trying to catch this error. You can easily check this, e.g., via any(table(time(zoo_object)) > 1) > The input/output from a recent R Console session might help, Not really, the data itself would have been much more helpful...and even better some simplified artificial data set. hth, Z ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
