Subject: Advice for the R-package of lme4
In-Reply-To: <50c26250-b96a-0cac-2ecc-aa2035572d63@gmail.com>
Thank you for your advice.
I appreciate your kindness.
Very sorry to bother you while you are busy.
I remembered making a backup of all R-packages before late April 2021.
Therefore, I loaded (downgraded) all packages and ran the program.
=====
Meanwhile, I have been in trouble of which the values in the output are
slightly different between late April 2021 and August 2021. The source
code, R environment, and csv files are the same (R-3.6.1 in Windows 10).
=====
For a different dataset made up before late April 2021, I could reproduce
the results.
So, the reason that I could not reproduce the results using the dataset,
which I posted you, seems that some problems have occurred in the period,
which I did not make a back up, such as OS update or consistency with other
packages.
I don't want to cause you any more trouble, so I'll do some more research
on my own for solving. Thank you very much.
Best regards
