So I installed and loaded the package Lathe.jl and it seemed to have a conflict with DataFrameMeta.jl. Now it seems my DataFrameMeta is corrupted with subset not working:
```julia
rawdf = @subset(rawdf, :has_iata .== "Yes", :iata .!= "9999999")
```
Error code:
```julia
ERROR: LoadError: UndefVarError: subset not defined

These are all of the things I have tried without luck:
Restarted VSCode
Wiped the library folder and the registry folder and reloaded all packages (without Lathe)
Updated DataFrameMeta
Using the gc command
I’ve also tried the simple DataFramesMeta.@subset() and get the same error
stopping short of wiping Julia entirely and starting over from scratch is there some option I am missing?

Seems like it was a recent known issue and that I need the most recent versions of DataFrames… Thinking that I had just wiped and reinstalled all the packages that they would be the newest version I thought to check and lo and behold:
I will post if this is the solution or not, but I am surprised that pkg.add(“DataFrames”) didn’t seem to add the latest version…
