How to dynamically construct a DimStack

[alex-s-gardner]

How can I construct a DimStack dynamically?

using DimensionalData
dX = X(collect(1:10))
dY = Y(collect(1:10))
varname = ["aa", "bb", "cc"]

das = [zeros(dX, dY) for v in varname]

How do I now construct a DimStack from the DimArrays contained in das? If I knew varname at compile time I would do:

ds = DimStack((aa=das[1], bb=das[2], cc=das[3]))

but I don't

Instinctually I want to do

DimStack(das, layers = varname)

-or-

DimStack(das, names = varname)

[tiemvanderdeure]

The keyword is called layersfrom

dX = X(collect(1:10))
dY = Y(collect(1:10))
varname = ["aa", "bb", "cc"]

da = zeros(dX, dY, Dim{:varname}(varname))
ds = DimStack(da; layersfrom = :varname)

DimStack(das; name=varname) should work?

It's not plural so it matches DimArray

[tiemvanderdeure]

DimStack(das; name=varname) should work?

Actually that doesn't work. The constructor with AbstractArray{<:DimArray} doesn't have a name keyword.

Ok we should fix that.

@alex-s-gardner you can also just set the name in the zeros constructor zeros(xs, ys; name=n)

Thanks! Both options work, thanks! I'll close this issue and open a separate one for:

DimStack(das; name=varname)

-and-

one for no DimStackkw documentation
