Mark did not post his response so I don't know what it is. How you do it may depend on your setup which was not entirely clear from the question since it started out as if the two series were the inputs and then seemed to be assuming the time ranges were. Here are a few possibilities assuming z1 and z2 from my prior post. Depending on what you want you may need to add 1. diff(range(time(merge(z1, z2, all = FALSE)))) diff(range(intersect(time(z1), time(z2)))) r1 <- range(time(z1)) r2 <- range(time(z2)) pmin(r1, r2)[2] - pmax(r1, r2)[1] The first one generalizes to N series immediately. The second does not but is slightly shorter (although abbreviation of the first could get that one even shorter). The last reduces the series to time ranges and then operates on those. ______________________________________________ R-help@r-project.org 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.
