UndefVarError: eachcol not defined

[ThomasBourany]

Cher Matthieu,

I have an issue with some incompatibilities btw different packages and FixedEffectModels
The one I can't solve gives me the following error :

reg(data, @formula(Y ~ A + L + K)) ## very basic ahah
ERROR: UndefVarError: eachcol not defined
Stacktrace:

[5] reg(::DataFrame, ::Formula) at /Users/thomasbourany/.julia/packages/FixedEffectModels/9HKQv/src/reg.jl:48

I think it has something to do with Compat (before it gave me the following error:
WARNING: both DataFrames and Compat export "eachcol"; uses of it in module StatsModels must be qualified) but now that I removed Compat (and GLM that was using Compat as well, with pkg.rm())

• Moreover, when I add fixed effect (as in your examples) it gives me :
  ERROR: MethodError: no method matching length(::Expr)
• When I add the clustering, it even spits out this:
  ERROR: UndefVarError: Vcov not defined
  reg(data, @formula(Y ~ L + K + fe(time_t) + fe(firm_st)), Vcov.cluster(:time_t, :firm_st))

I feel the three points are linked!

Also, there was an incompatibility with MixedModels that prevented me to even add the package. But this problem was solved when I removed MixedModels

I have Julia v1.0.3 and I also updated most of my packages beforehand.
Sorry if it is something trivial,
Thanks, Merci beaucoup!

The current version of FixedEffectModels, with the syntax explained in the README, works for Julia 1.1. (and above). It'd a bit hard for me to make sure that it works for versions of Julia below 1.1.

[matthieugomez]

Ok I've modified the package to allow Julia 1.0

If you try

]add FixedEffects#master
]add FixedEffectModels#master

everything should work. Let me know if not

[ThomasBourany]

Oh thank you for your quick response,

Unfortunately, it doesn't seem to work. After removing Pkg.rm(), I added the 1st folder (fixed effects) and adding the 2nd one gives me this error:

(v1.0) pkg> add FixedEffectModels#master

This error carries on even when I add the package -- Pkg.add("FixedEffectModels") -- behorehand.

[matthieugomez]

Yes you need to update to StatsModels 0.6. Did you try ]update? If it does not work you probably have a package that is not compatible with StatsModels 0.6, and therefore with the current version of FixedEffectModels.

Ok, I think I figured out part of it:
For some reasons, ]update and Pkg.update() were not updating StatsModels from 0.5 to 0.6.6,
After Pkg.rm("FixedEffectModels"), it also removed StatsModels 0.5, and I could add the most recent one:
pkg> add StatsModels@0.6

In this case, I could have added FixedEffectModels#master

However, the error remains when using regression with or without fixed effects -- the error is exactly the same as in my first post above.
reg(data, @formula(Y ~ A + L + K))

I think I'll download Julia 1.1. in the near future !
Thanks !
