Dear Eric, thank you for that observation.
I realised that some of the participants have duplicated “survey_start” dates
and when I corrected this, the code works.

Hi Kevin,
I think there are issues with Rui's proposed solution. For example, if there
are rows in
- which(names(myDF1) == "pf_mcl")
merge(myDF1[-i1], myDF2, by = "studyno")
Hope this helps,

I'm trying to populate the column “pf_mcl” in myDF1 with values from myDF2,
where rows match based on column "studyno" but the solutions I have found so
far don't seem to be giving me the desired output.
Below is a snapshot of the data.frames.

HI Jeff, it’s been an uphill task working with the dataset and I am not the
first to complain. Nonetheless, data-cleaning is ongoing and since I cannot
wait for that to get done, I decided to make the most of what the dataset looks
like at this time. It appears the process may take a while.

The dataset is from a study where individuals are given drugs and followed up
