Dear R users,

Could you share your knowledge on following problem:

Suppose we have dataframe:

ID     TIME                         Data1         Data2        Data3
........... Data700
1.    2013-01-01 00:00:00       34                53             66
............    55
2.    2013-01-01 00:00:01       333               4               5
............     50
3.    2013-01-01 00:00:02       and so on
4.    2013-01-01 00:00:03       and so on
5.    2013-01-01 03:00:45       44                33               4
.............     66
6.    2013-01-01 03:00:46       46                35               7
.............     6

Notice that between ID 4 and ID 5 there is a gap, that instrument was
turned off. It started automatically in 2013-01-01 03:00:45 and continues
till the next turn off.
What I need R to do, is to find these gaps, and insert missing time values
with empty Data lines to have no gaps in time and empty (or NA) values in
data place:


ID     TIME                         Data1         Data2        Data3
........... Data700
1.    2013-01-01 00:00:00       34                53             66
............    55
2.    2013-01-01 00:00:01       333               4               5
............     50
3.    2013-01-01 00:00:02       and so on
4.    2013-01-01 00:00:03       and so on
5.    2013-01-01
00:00:04
<- time with empty (or NA) data values inserted
6.    2013-01-01
00:00:05
<- time with empty (or NA) data values inserted
7.    2013-01-01
00:00:06
<- time with empty (or NA) data values inserted
................
and so on, until the time when instrument works again:
      2013-01-01 03:00:45       44                33               4
.............     66
      2013-01-01 03:00:46       46                35               7
.............     6



All your suggestions will be appreciated!
