Abstract:
|
SciDB is an open-source database that organizes data in n-dimensional arrays. Interesting SciDB features include parallel processing, distributed storage, ACID transactions, efficient sparse array storage, and native linear algebra operations. The "scidb" package for R provides two general ways to interact with SciDB from R:
1. By running database queries from R, optionally moving data between R data frames and SciDB arrays.
2. Through a sparse n-dimensional array object class for R. The arrays mimic standard R arrays, but operations on them are performed by the SciDB engine. Data are materialized to R only when requested.
We illustrate using SciDB and R with a few examples including computing a truncated singular value decomposition of a large, sparse matrix, and bi-clustering of large SciDB arrays using the biclust package.
