Hi everybody,
I’m working under Julia 0.5.1 and I face this problem below:

Error evaluating AirplaneRealStats5.9.jl

Presumably you are trying to adding a method to Base.min function.
As the error message indicates, you need to explicitly import Base.min.

Example:

type MyType
    x::Int
end

import Base.min
min(a::MyType, b::MyType) = min(a.x, b.x)

or else fully specify:

Base.min(a::MyType, b::MyType) = min(a.x, b.x)

Note also that generally speaking, it is unnecessary to extend the min function; just extend < or isless as appropriate (see the documentation for when to extend each).

Perfect.error solved. Thank you for your reactivity
