Dataframe, Data manipulation toolbox similar to R data.frame At an mature development stage. [http://hg.code.sf.net/p/octave/dataframe hg] *Maintainer: Pascal Dupuis *Contributors: *Package: [http://octave.sourceforge.net/dataframe/ dataframe]
Overhaul introduction. Add subsections.
This package permits to handle complex (both in the sense of complex numbers and high complexity) data as if they were ordinary arrays, except that each column MAY possess a different type.
