Hello,
The message is not about lengths, it's about sets. It means that the two
factors, compkey and armkey don't have the same levels, which you can
see with
levels(compkey)
levels(armkey)
and test for equality.
Also, your post's prologue doesn't have a direct relation with the
error, you could have skipped the lines up to, including, sink(). It's
much better to provide an actual data example:
dput( head(outcome, 50) ) # paste the output of this in a post.
Hope this helps,
Rui Barradas

Why the error is coming? even though the length of outcome.new$compkey and
outcome.new$armkey were exactly same.
Can anyone help?
