I'm working on some two-dimensional tables of data, where some data are numerical, while other aren't. I'd like to use numarray's numerical capabilities with the numerical parts (columns) while keeping the data in each row together. (I'm sure this generalizes to more dimensions, and to sub-arrays in general, not just rows.)
You may want to have a look at PyTables (http://pytables.sourceforge.net). It's designed to be used in scenarios similar to that you are exposing. It supports Numeric objects and although columns in tables are not automatically converted to Numeric o numarray objects, you can build them on the flight easily using its powerful selection capabilities. It uses HDF5 (http://hdf.ncsa.uiuc.edu/HDF5/) format to save its data, so you can read PyTables files in a variety of languages and platforms. Cheers, Francesc Alted
