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
