data frame class

[waynenilsen]

I am considering implementing something like the python pandas DataFrame which is usually used to hold statistical items (possibly mixed types) with column and row indexes. I think this is the library to do that in unless you think it should be implemented externally. I wanted to get your view on it before implementing this under the scirust umbrella.

If you think this is the library for it, where in the structure should the source file go? Possibly a new folder under src/?

Hi,
I would agree to have it in our code base. What about having it inside the src/stat ? I mean statistical work requires a lot more flexibility in data representation than a bare bones Matrix can provide. We can have a submodule inside src/stat (say src/stat/data) which are used for DataFrame and similar data structures which could be used for smart representation of statistical data.

Does that sound Okay?

BTW, looks like the daily build broke again today. So will try to fix it.

Looks like the new build error is not even in the source code. I am wondering if something has gone wrong in the compiler itself today.

The build it back now (without any change from me). So it was indeed a compiler/cargo issue.
