I have an issue with the most recent LMest package. I run this model on a large panel data, 868 individuals, across 55 time periods. The code produces the following error messages:

Error in Ops.data.frame(id, idu[i]) : 
  ‘==’ only defined for equally-sized data frames

I was able to run the code on the same data before Nov-2021. Can anyone provide any suggestions? I suspect it is caused by the update on one of the dependencies packages. But I don't know which one, so I cannot reroll to old version.

Thanks,

James Li

    Welcome to SO, James Li! Questions on SO (especially in R) do much better if they are reproducible and self-contained. By that I mean including attempted code (please be explicit about non-base packages), sample representative data (perhaps via `dput(head(x))` or building data programmatically (e.g., `data.frame(...)`), possibly stochastically), perhaps actual output (with verbatim errors/warnings) versus intended output.
