|I need help in merging two different datasets. I am merging
by date and I want to propagate observations from one
dataset to the corresponding dates. One dataset has a
unique date for each day of the month, while the other
dataset has same date for different patient visits. For
example I want to spread an observation on the 31DEC2008
from one dataset to several observations with the same date
on a second dataset for all the patients who visited on
that date. I have tried to merge the two and the result is
not what I wanted. Instead I get a dataset whereby all the
dates have missing values where observations from the first
datset should have spread.
