Hi folks,
Here's one I've been struggling with for a couple of days:
I have a file with telemetry data for n individuals. For each individual I have data on a number of days, over the course of a couple of years. On any given day, I have from 1 to several "fixes" for an individual. Fixes range from 1 to 3, with 3 being the "best". Note that I do not necessarily have data for all individuals on a given day.
What I want to do is extract the row with best fix for each individual, on each day for which I have data for that individual. If there is more than one best fix for an individual on a given day, then I want to choose the first best fix (temporally). Right now my data is set up with columns:
INDV DATE TIME FIX ....other attributes
INDV = unique code identifying the individual
The data is sorted by INDV, then by DATE, then by TIME.
I figured I could do this using nested IF statements, where "TRUE" would be added to a new column (e.g., HIGHFIX) in the row of the first highest fix on each day for each individual, but have not been successful in doing this. I've also tried conditional formatting. Again, no success here.
Any thoughts/ideas would be much appreciated. It's a very large dataset, so I'd like to avoid doing this manually.
Cheers and thanks,
Jenn
