Andrei suggested posting more widely.
I believe it is easier and more effective to start on the
research side. D will need: [snip]
Great list, but tons of work!
A journey of a thousand miles ...
I tried to start creating a data table type object by
investigating variantArray:
http://forum.dlang.org/thread/hhzavwrkbrkjzfohc...@forum.dlang.org but hit the snag that D is a static programming language and may not allow the kind of behaviour you need for creating the same kind of behaviour you need in data table - like objects.
I envisage such an object as being composed of arrays of vectors
where each vector represents a column in a table as in R - easier
for model matrix creation. Some people believe that you should
work with arrays of tuple rows - which may be more big data
friendly. I am not overly wedded to either approach.
Anyway it seems I have hit an inherent limitation in the
language. Correct me if I am wrong. The data frame needs to have
dynamic behaviour bind rows and columns and return parts of
itself as a data table etc and since D is a static language we
cannot do this.
