pass variable name to Dataset as string or symbol

[lazarusA]

currently we do

ds = Dataset(z = YAXArray(rand(10)))

YAXArray Dataset
Shared Axes: 
Dim{:Dim_1} Sampled{Int64} Base.OneTo(10) ForwardOrdered Regular Points
Variables: 
z, 

and the variable name is z, but is there a way to pass a name as an extra argument ? as a symbol or string? The following don't work :(

ds = Dataset(:z = YAXArray(rand(10)))
ds = Dataset("z" = YAXArray(rand(10)))

let's say we have >50 variables and we have a list for them, then using that list would be ideal.

You can construct a NamedTuple from your list of variables and list of variable names and then splat this inside the Dataset call.

keylist = (:a, :b,:c)
varlist = (YAXArray(rand(10)), YAXArray(rand(10)), YAXArray(rand(10)))
julia> YAXArrays.Dataset(;(;zip(keylist,varlist)...)...)
YAXArray Dataset
Shared Axes: 
Dim{:Dim_1} Sampled{Int64} Base.OneTo(10) ForwardOrdered Regular Points
Variables: 
a, b, c,

Thanks, for one variable would be like this:

keylist = (:a, )
varlist = (YAXArray(rand(10)),)
YAXArrays.Dataset(;(;zip(keylist,varlist)...)...)

it works, but its really cumbersome, maybe having an enhancement to make this more user friendly would be a good, @meggart .

You can shorten that to the following, which is still obscure but a bit better:

julia> YAXArrays.Dataset(; (keylist .=> varlist)...)
YAXArray Dataset
Shared Axes: 
Dim{:Dim_1} Sampled{Int64} Base.OneTo(10) ForwardOrdered Regular Points
Variables: 
a,

nice! final solution

 YAXArrays.Dataset(; (:a => YAXArray(rand(10)),)...)
