setname! doesn't allow Symbol as a name

[injun6]

setname! function doesn't allow the name with Symbol format

For example,

a = NamedArray(zeros((3, 3)))
setnames!(a, ["a", "b", "c"], 1)

works well with following result:

3×3 Named Matrix{Float64}
A ╲ B │   1    2    3
──────┼──────────────
a     │ 0.0  0.0  0.0
b     │ 0.0  0.0  0.0
c     │ 0.0  0.0  0.0

However, for the index name with Symbol format like below:

a = NamedArray(zeros((3, 3)))
setnames!(a, [:a, :b, :c], d=1)

returns following error:

ERROR: TypeError: in setnames!, in second argument, expected String, got Type{Symbol}

Any plans to update the problem?

This is intentional. The type of a has Strings as index type. Setting the index to a Symbol is a type violation.

You can initialize a different NamedArray with Symbols` as index.

a = NamedArray(a, ([:a, :b, :c], [:a, :b, :c]))
