I spent some more time to understand the examples .. it helped a bit. 

But there is still one issue.

Taking example data (my first on, hope it is not confusing ;-)  ) like:


library(latticeExtra)
library(zoo)


#  example Data

timeVect1=seq(as.Date("1990-01-01"), as.Date("2010-12-31"), by="day")
timeVect2=seq(as.Date("1993-01-01"), as.Date("2010-12-31"), by="day")

df1=data.frame(a=runif(length(timeVect1), max=200),
b=runif(length(timeVect1), max=250))
df2=data.frame(a=runif(length(timeVect2), max=2),
b=runif(length(timeVect2), max=1.5))

ts1=zoo(df1, timeVect1)
ts2=zoo(df2, timeVect2)


# Adding some NA values

ts1$a[sample(1:trunc(length(timeVect1)/2), 2000)]=NA
ts1$b[sample(trunc(length(timeVect1)/2):length(timeVect1), 2000)]=NA

ts2$b[sample(1:trunc(length(timeVect2)/2), 2000)]=NA
ts2$a[sample(trunc(length(timeVect2)/2):length(timeVect2), 2000)]=NA




xyplot(ts1, panel = function(x, y, ...) {
        panel.grid(h = 10, v = 10, col = "grey", lty = 3)
        panel.xblocks(x, is.na(y), ..., col="RED")
panel.xyplot(x, y, ...)
})

So I managed to plot the missing data of ts1 to the corresponding panel,
but, how do I add the missing data from ts2 to the plot that show the
data from ts1 for the columns a and b??

Thanks for your efforts. 

Stefan
