Factors in Rho

[Steve Nunez]

Hi All,

I'm in the process of adding factors to the data-frames package, and rather than reinvent the wheel, I thought I'd look for some existing work to build on.

Marco's factors in Rho look promising, but there's no documentation, tests or examples. Has anyone got any examples of this working in practice?

Cheers,

    - Steve

I had to clean up the list, as nearly all members were marked 'no mail' for some reason. Some folks joined a long time ago; if the list isn't relevant you might want to unsubscribe.

Hi Steve

I know they work in theory :) :) :)

The basic object and their constructors should be somewhat ok.  What is missing are all the other functions that are usually used with factors in R.  Although I kind of think that maybe some of them have a quite convoluted semantics, plus nomenclature that is confusing to functional programming types (I am talking about myself?)

All the best

Marco

Hi Marco,

Anything planned for the short-term for labels? I'll write some tests for this if you want to nudge factors forward. It looks like it is nearly a drop-in for data-frames.
