scidb (version 1.1-2)

scidbconnect: Connect to a SciDB database.

Description

Connect to a SciDB database.

Usage

scidbconnect(host=options("scidb.default_shim_host")[[1]],
             port=options("scidb.default_shim_port")[[1]],
             username, password)

Arguments

host

The host name or I.P. address of the SciDB database instance to connect to (character).

port

The integer port number of the SciDB database simple HTTP service. The default shim ports are 8080 (open) and 8083 (SSL encrypted).

username

Optional authentication username (character).

password

Optional authentication password (character).

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.

Use the optional username and password arguments to authenticate the connection with the shim service. Authenticated connections require an encrypted connection with shim, available by default on port 8083.
