pass column names to :fastmath/ols models

[daslu]

fastmath.ml.regression/lm supports a :names option that controls the names of the coefficients when the model is printed.

In the metamorph.ml context, our data originate from a dataset, so we may use the column names for that.

@daslu
did you mention this as one of the changes you wanted to do, if /when we would add the model to tablecloth itself ?

(which I am not sure, we should do, as the model is available here)

[daslu]

Sorry for missing this message earlier.

Yes, I think we should have a Tablecloth function to take care of that eventually.

[behrica]

are you refering to pass :names as written here:
https://generateme.github.io/fastmath/clay/ml.html#lm

If so, then fixing #27 will fix this as well.

[daslu]

Yes

[daslu]

Yes, but I am proposing this will happen automatically -- the dataset column names will be passed as :names by default.

@daslu
I don't understand what you mean with this change request.
Maybe you can do an PR ?

[daslu]

Thanks, good idea, I will do a PR.

(I mean something like we did in Tablemath:
https://github.com/scicloj/tablemath/blob/a667be6/src/scicloj/tablemath/v1/api.clj#L242
The option map to lm can automatically receive the column names of the dataset.)
