If `reformat` is implemented, then `fit` is not required to accept tables. Rather it accepts the form of data output by `reformat`. I thought the [docs](https://alan-turing-institute.github.io/MLJ.jl/dev/adding_models_for_general_use/#Implementing-a-data-front-end) were clear on this...

How about, following the cited sentence, we add the new sentence: "An exception to this requirement occurs when a data front-end is implemented; see [Implementing a data front-end](@ref) below."

@bensadeghi Perhaps you care to comment on this one?

The test in question is equivalent to `node_impurity/wsum > 1e-7` and it's a little odd that it isn't written that way, because the impurity is already computed. Anyway... I suppose...

I've also encountered this. If I try `Pkg.build(RCall)`, the build hangs: ```julia julia> Pkg.build("RCall") Building Conda → `~/.julia/scratchspaces/44cfe95a-1eb2-52ea-b672-e2afdf69b78f/6e47d11ea2776bc5627421d59cdcc1296c058071/build.log` Building RCall → `~/.julia/scratchspaces/44cfe95a-1eb2-52ea-b672-e2afdf69b78f/72fddd643785ec1f36581cbc3d288529b96e99a7/build.log` Progress [====================> ] 1/2 ```

For me its macOS: ```julia julia> versioninfo() Julia Version 1.8.2 Commit 36034abf260 (2022-09-29 15:21 UTC) Platform Info: OS: macOS (x86_64-apple-darwin21.4.0) CPU: 12 × Intel(R) Core(TM) i7-8850H CPU @ 2.60GHz WORD_SIZE:...

Mmm. Sometime, long ago, when I first installed Call I seemed to have set `R_HOME` set to "\*" in my .bashrc, which according to RCall docs should trigger a julia-local...

For the record, I've just tried today without changing R_HOME and `Pkg.build(Call)` worked (with no change to my weird R_HOME). I have not idea what changed. R was installed using...
