How to convert Char to Float? What wrong ?
julia> eltype(sort(unique(dane[:,4]))[3])
Char
julia> (sort(unique(dane[:,4]))[3])
"-.097"
julia> convert(Float64(sort(unique(dane[:,4]))[3]))
ERROR: MethodError: `convert` has no method matching convert(::Type{Float64},
::UTF8String)
This may have arisen from a call to the constructor Float64(...),
since type constructors fall back to convert methods.
Closest candidates are:
call{T}(::Type{T}, ::Any)
convert(::Type{Float64}, ::Int8)
convert(::Type{Float64}, ::Int16)
...
in call at essentials.jl:56
