Just place a point with an NA value between the two segments. Here is one way to do it in zoo:
set.seed(123) library(zoo) # create sample data tt <- c(1:1000, 1200:2000) z <- zoo(rnorm(length(tt)), tt) # this will fill in omitted values with NAs z <- as.zoo(as.ts(z)) plot(z) On Thu, May 28, 2009 at 3:05 PM, <josef.kar...@phila.gov> wrote: > I have a time series of about 1500 measurements.
