>however it provides the basic functionality of an `AbstractDataFrame` a bit tangential here, actually we don't need `DataFrames.jl` for any "real" functionality, mainly the printing and some interface I got...

For filling histogram, likely you will have more than a few histograms to fill anyway so jam all the code into a columnar command is hard to maintain later. https://github.com/Moelf/FHist.jl...

If you have a particular RDataFrame use-case in mind, that is nice AND **scalable** such that you can do a full-blown analysis with just RDataFrame query-y commands, I'm happy to...

yes, your example makes a copy at the end, because the `Query` produces a collection of `NamedTuple`s. >not having the explicit event loop I doubt real world analysis expressed in...

btw there's a CMS [NanoAOD](https://github.com/tamasgal/UnROOT.jl/blob/master/test/samples/NanoAODv5_sample.root) in the `./test/samples` of this repo, it's easier to have a common test sample so we copy-paste and run. (accessing opendata turns out to be...

I would do your example this way: ```julia julia> using UnROOT, LVCyl, FHist julia> const events = LazyTree(ROOTFile("Run2012BC_DoubleMuParked_Muons.root"), "Events"); julia> const h = Hist1D(Int; bins = -1.:0.005:2.5); @time for evt...

Those are way too long and I can't quite figure out where does some functions in string comes from for example `pt_cuts()` in the second link (`.h` file somewhere?). Is...

My fear is that due to the auxiliary code around making plots and histogram and name things, it won't be clear to readers because it's too long to hold in...

ok let me try to write a blog-like article and compare a few "kernel" functions like that and build up to a mini full analysis with two cuts and filling...

I'm writing the said document already and want to put some key observation here for posterity without referring to the full document. This is based on example of: https://root.cern/doc/master/df103__NanoAODHiggsAnalysis_8py_source.html, the...
