```
extend_to_length!(v::AbstractRange, n) = range(first(v), step = step(v), length = n)
function extend_to_length!(v::AbstractVector, n)
vmax = isempy(v) ? 0 : ignorenan_maximum(v)
extend_by_data!(v, vmax .+ (1:(n - length(v))))
end
extend_by_data!(v::AbstractVector, x) = isimmutable(v) ? vcat(v, x) : push!(v, x)
function extend_by_data!(v::AbstractVector, x::AbstractVector)
isimmutable(v) ? vcat(v, x) : append!(v, x)
end
```

It seems that "isempy" should be "isempty"
