Allowing a preexisting vector to contain missings later on

New to Julia
1

Following

A = [1.0, 2.0]
A = Union{Float64,Missing}[1.0, 2.0]
A[1] = missing          # Union{Missing, Float64}[missing, 2.0]

tried

B = [1.0, 2.0]
missB = Union{Float64,Missing}B        # errors

How may I accomplish this? Thank you in advance.

Array{Union{Float64,Missing}}(B)

the syntax of T[1,2,3] works because getindex(T, 1,2,3) is understood (specially) as making a vector of element type T. The TB is understood to be T*B which doesn’t make sense.

@jling thank you for your reply. Now I am getting ERROR: LoadError: MethodError: no method matching Union{Missing, Float64}(::Vector{Float64})

You can also use allowmissing(v)

Yes but its defined for arrays as well in Missings.jl (I didn’t realize it was in Missings earlier)
