You may be seeing some of the overhead of using `DataStreams` when reading the Feather file in Julia. I have been encountering problems myself with large feather files (about 5...

It appears that this issue is because the `Arrow` package needs to be updated for changes in `CategoricalArrays`. I think the Arrow structure for a `CategoricalArray` or a `PooledArray` should...

It appears as if https://github.com/ExpandingMan/Arrow.jl/pull/52 already addresses this issue.

Thanks for the replies @johnnychen94 and @davidanthoff . Can you point me to some information on JULIA_DEPOT, David? I should know what that environment variable refers to but I don't....

I found the description of JULIA_DEPOT in https://docs.julialang.org/en/v1/manual/environment-variables/

I'm fine with individual users having their own package repositories as it quickly becomes too much of a headache to try to maintain a system-wide package repository. I guess I...

That seems reasonable. Thanks for considering this. For the time being we will go back to having several different `julia-1.x.y` links in our equivalent of `usr/local/bin/`

I probably put the `isna` function in `RCall` initially because I was duplicating the R API in Julia code and it was before `Missing` was part of Julia. It would...

I think I have tracked it down a bit more. On a 64-bit system R uses 32-bit integers in BLAS/LAPACK calls whereas Julia will use 64-bit integers. Fortunately I am...

Yes, I do use the official Julia binaries. I was comparing some linear-algebra-intensive fits in lme4 and MixedModels and, for fairness, I really should have them both use the same...
