Hello, I need to subset my data to only look at the parts that have "holes"
in it. I already have a formula to get rid of inconsistencies, but now I
need to look only at the problem data to reconfigure it. In my data set
where there are multiple "cycles" per "patient," and I want to highlight
the patients who have a variable was not measured every cycle.
Here's a similar example of the data:
Patient, Cycle, Variable1, Variable 2
A, 1, 4, 5
A, 2, 3, 3
A, 3, 4, NA
B, 1, 6, 6
B, 2, NA, 6
C, 1, 6, 5
C, 3, 2, 2
So in this case, I would want Patient A and Patient B, but not Patient C.
Thanks!
