Thanks Iain. So then how could I fix it?

[julia-users] Re: Installing Julia Studio properly on Windows 7 - Step by Step Instructions
Hi, After I started Julia Studio I received this message in the Output Console window: ERROR: package directory C:\Users\pamela_j\Documents\v0.3 doesn't exist; run Pkg.init() to create it. in error at error.jl:21 in cd at pkg/dir.jl:25 while loading C:\Program Files\JuliaStudio-0.4.5\julia-studio\share\julia-studio\Console\Console.jl, in expression starting on line 1 Therefore, I don't have even the chance to write any command in the Console window as Julia doesn't appear. What can I do? I hope you can help me, Thanks, Pam.

Re: [julia-users] pdf of a multivariate distribution
Thanks a lot John for your answer! I'm starting in Julia so I'm still in
the learning curve...
Do you know how I can convert Array{Float64, 2} to Array{Float64, 1}?
Thanks again!
Pam.

In Julia, anything with a description like 1x27 Array{Any,2} is a matrix,
not a vector.
Also, it's not the right kind of vector because it has no numeric type
restriction. It needs to be a vector of Float64 values, like you'd get from
doing something like:
[1.0, 2.0, 3.0]
