[R] Adding in Missing Data

[Jeff08]

Sample Data.Frame format

Name is Returns.names

            X       id ticker      date_ adjClose totret RankStk
427225 427225 00174410    AHS 2001-11-13    21.66    100    1235


"id" uniquely defines a row


What I am trying to do is add missing data for each ID.

Important Information: Date is not continuous, the data points are for
trading days, so weekends/certain holidays are off

x<-unique(Returns.names$date_) gives me the list of all the possible trading
days.

For days that are missing, I would like to add a row for that date & the
same totret as the previous day.

I cant think of an easy way to do this
