v0.7.5

julia> using StatsModels

julia> data = (; x=[true, false], y=randn(2))
(x = Bool[1, 0], y = [0.6397358258449067, -1.1950505390298463])

julia> f = apply_schema(@formula(y ~ x), schema(data, Dict(:x => EffectsCoding())))
ERROR: MethodError: no method matching StatsModels.ContrastsMatrix(::Matrix{Float64}, ::BitVector, ::Vector{Bool}, ::EffectsCoding)
The type `StatsModels.ContrastsMatrix` exists, but no method is defined for this combination of argument types when trying to construct it.

Closest candidates are:
  StatsModels.ContrastsMatrix(::M, ::Vector{U}, ::Vector{T}, ::C) where {U, T, C<:AbstractContrasts, M<:(AbstractMatrix)}
   @ StatsModels ~/.julia/packages/StatsModels/kgR1k/src/contrasts.jl:110
  StatsModels.ContrastsMatrix(::StatsModels.FullDummyCoding, ::AbstractVector{T}) where T
   @ StatsModels ~/.julia/packages/StatsModels/kgR1k/src/contrasts.jl:285
  StatsModels.ContrastsMatrix(::C, ::AbstractVector) where C<:AbstractContrasts
   @ StatsModels ~/.julia/packages/StatsModels/kgR1k/src/contrasts.jl:160
  ...

v0.7.4

julia> f = apply_schema(@formula(y ~ x), schema(data, Dict(:x => EffectsCoding())))
FormulaTerm
Response:
  y(continuous)
Predictors:
  x(EffectsCoding:2→1)

The most minimal MWE:

julia> ContrastsMatrix(EffectsCoding(), [true, false])
ERROR: MethodError: no method matching ContrastsMatrix(::Matrix{Float64}, ::BitVector, ::Vector{Bool}, ::EffectsCoding)
The type `ContrastsMatrix` exists, but no method is defined for this combination of argument types when trying to construct it.
