scidb (version 1.0-1)

scidbconnect: Connect to a SciDB database.

Description

Connect to a SciDB database.

Usage

scidbconnect(host = "localhost", port = 8080L)

Arguments

host
The host name or I.P. address of the SciDB database instance to connect to (character).
port
The port number of the SciDB database simple HTTP service to connect to (integer).

Value

  • NULL is invisibly returned. SciDB connection errors are propagated to R and may be handled with the usual R error handling mechanisms.

Details

The SciDB connection state is maintained internally to the scidb package. We internalize state to facilitate operations involving scidb objects.

Thus, only one open SciDB connection is supported at a time.

One may connect to and use multiple SciDB databases by sequentially calling scidbconnect between operations. Note that scidb objects are not valid across different SciDB databases.
