SciDB interface package.

Description

The scidb package provides basic functions that move data between R and SciDB and issue SciDB queries.

The package defines two R classes that facilitate programming with SciDB. The scidb class defines an n-dimensional sparse array class. The scidbdf class defines a data frame class. Data for scidb and scidbdf objects are backed by the SciDB database and operations on them are conducted by SciDB.
