[R] zoo timeserie continuous? complete with NaN

[marcg]

dear r-list

I have a zoo object with 2 objects and time:

looks like:
2005-12-31 12:00:00   NA          NaN
2005-12-31 13:00:00   NA          NaN
2005-12-31 14:00:00   NA          NaN
2005-12-31 15:00:00   NA          NaN
2005-12-31 16:00:00   NA          NaN
2005-12-31 18:00:00   NA          NaN
2005-12-31 19:00:00   NA          NaN
2005-12-31 20:00:00   NA          NaN
2005-12-31 21:00:00   NA          NaN
2005-12-31 22:00:00   NA          NaN
2005-12-31 23:00:00   NA          NaN

its much longer though...

As you can see, the values for 2005-12-31 17:00:00 miss. How can I let R show me if the timeseries is continuous and if not, to fill up with NaN values (i need a continuous timeseries). is there a function like complete.timeseries(missing=NA)?

Thanks fpr your help
