Code example in JOSS paper does not work

[felixcremer]

Trying the code example in the JOSS paper I first got an residual not defined error, but when I replace residual with data I get the following error:

julia> flags = significant_transitions(results, signif)
ERROR: MethodError: no method matching length(::Symbol)

Closest candidates are:
  length(::Combinatorics.Partition)
   @ Combinatorics ~/.julia/packages/Combinatorics/Udg6X/src/youngdiagrams.jl:8
  length(::DataStructures.EnumerateAll)
   @ DataStructures ~/.julia/packages/DataStructures/95DJa/src/multi_dict.jl:96
  length(::Pkg.Types.Manifest)
   @ Pkg ~/.julia/juliaup/julia-1.10.2+0.x64.linux.gnu/share/julia/stdlib/v1.10/Pkg/src/Types.jl:315
  ...
