R help - Jul 2010 - CBIND / MERGE two time series objects along time (overlapping indices, redundant data)

Hi there,

I need to merge/bind two time series objects (from RPackage: timeSeries) by 
column. The theory is laid out nicely, even for overlapping indices. 


In my example, I have overlapping indices ("01.01.2001"), where in one
time
series I have one data point and in the other redundant data. Default usage of 
merge and cbind would lead to the result that the one data point would be 
replicated (see example below). However, I do not like the replicating feature 
and would like to have the NA's filled instead.

Desired output, would be:
                    TS.1 SS.2
2001-01-01 23.1 23.1
2001-01-01 NA  23.4

Is there a slick way to produce above result? Thank you for your answer - help 
is really appreciated.

Kind regards,

Bernhard.

require(timeSeries)
date <-timeDate("01.01.2001", format = "%d.%m.%Y")
test1 <- timeSeries(c(23.1), charvec = date)
test2 <- timeSeries(c(23.1, 23.4), charvec = c(date, date))
colnames(test2) <- "SS.2" 
merge(test1, test2)
