Missing not defined

New to Julia
1

Hi,

I have been using the following to replace missing values with zero but it’s now failing and I can’t see why.

replace!(df.myfloat64field, missing => 0.0)
returns
ERROR: UndefVarError: missing not defined

same problem when I try df = DataFrame(A=2,B=missing)

I’m using Julia 1.6.2 but I did try to upgrade to Julia 1.6.3 and 1.6.4 but the Language server gets stuck starting so I reverted. I have noticed strange problems in the past when I change versions. I tried adding Missings but no change. Do I need to do some sort of refresh or clearing of files when I change versions?

Thanks
Steve

All I can help with is letting you know it is supposed to work :slight_smile:

Version 1.6.3 (2021-09-23)
 
julia> using DataFrames

julia> df = DataFrame([[1,missing,3], [10,20,30]], ["a", "b"])
3×2 DataFrame
 Row │ a        b
     │ Int64?   Int64?
─────┼─────────────────
   1 │       1      10
   2 │ missing      20
   3 │       3      30

julia> replace!(df.a, missing => 0.0)
3-element Vector{Union{Missing, Int64}}:
 1
 0
 3

It may help to make the example more minimal. What happens if you restart Julia and just type

julia> missing

into the repl? And what is your full versioninfo() output? What if you type Base.missing?

Thanks DNF,

I changed my code to include your suggestion:

println("Base.missing ",Base.missing)
println("Verion Info ",versioninfo())
replace!(df_Value.Quantity, missing => 0)

and when I run the file using ^ F5 the output is

Base.missing missing
ERROR: LoadError: UndefVarError: versioninfo not defined

But from the repl I get

julia> versioninfo()

Something seems to be seriously broken in your install: your Julia 1.6 uses JULIA_HOME = C:\JuliaPro-1.3.1-2\Julia-1.3.1\bin. I suggest removing that old JuliaPro version and reinstalling Julia from scratch.

Thanks, juliapro was previously removed but I uninstalled everything including the vscode extension and the Julia updater from the Microsoft store and re-installed 1.7.0 via direct download and it works as expected now. All versions after 1.6.2 were also failing to start the language server and that problem is also fixed. Thanks for your help.
