Re: [julia-users] Re: rownames in data matrices
Interesting to follow that discussion, thanks. I can see the philosophical arguments not to, though I think rownames are intuitive and nice.

Re: [julia-users] Re: rownames in data matrices
DataFrame behavior has been discussed many times, eg. https://groups.google.com/d/msg/julia-users/8UFnEIfIW0k/QNEustV9BQAJ. Short answer: having row names is considered, but a bit of a philosophical difference, so it's not guaranteed to happen at some point.

Re: [julia-users] Re: rownames in data matrices
Thanks, it looks like that package will do the trick!

Re: [julia-users] Re: rownames in data matrices
AFAIK https://github.com/davidavdav/NamedArrays.jl already does this and is maintained actively.

[julia-users] Re: rownames in data matrices
Hello colleague, in the first order i think this could be emulated by a dictionary mapping the row name to an index into a matrix or DataFrame. Afaics calling this a 'misfeature' comes from trying to make a matrix datatype that has row names by default and many people with numerics/engineering background reserve the name matrix for the simplest possible form: rectangular array with single number entries and integer row and column indexing. So what you look for: a rectangular collection accessible with both row and column index as names is something new and should have different name. You could browse the dataFrames development and see if there are enough hooks to extend this. Bringing this into julia as package (written in julia) should not be that complicated if defined clearly (but still, someone is needed to implement).
