plotting time series with data gap using type line- but do not want to connect gap with line

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)

I have a time series of about 1500 measurements. ?There are sporadic data gaps. ?I would like to plot the time series with type "line". ?I only want a line to connect the periods with data; I don't want a line to connect the points across a data gap. ?Is there a function or recommended method to deal with this? For example there are 2000 days days 1:1000 each have one measurement of temperature days 1001: 1199 have no data days 1200:2000 each have one measurement of temperature I want the plot to connect points 1:1000 with a line, and to connect points 1200: 2000 with a different ?line. I don't want a line to connect points 1001:1200. I searched the help archives and google but couldn't find anything. Any advice? JK ? ? ? ?[[alternative HTML version deleted]]
