netWorkSpace-class: NetWorkSpaces Objects
In nws: R functions for NetWorkSpaces and Sleigh

Description Objects from the Class Slots Methods Examples

NetWorkSpaces provides a framework to coordinate R programs. NetWorkSpaces objects represent a generalized workspace or environment. Two or more R programs communicate data by storing it in and retrieving it from the NetWorkSpace object.

Objects can be created by calls of the form
netWorkSpace(wsName, serverHost, port, useUse, serverWrap, ...)
or
new("netWorkSpace", wsName, serverHost, port, useUse, serverWrap, ...).

wsName: name of the netWorkSpace to be created.
serverHost: host name of the server this netWorkSpace will be connected to. By default, local machine is used.
port: port number of the server this netWorkSpace will be connected to. Default port number is 8765.
useUse: a logical value indicating whether ownership will be claimed for this netWorkSpace. By default, useUse=FALSE, which means ownership will be claimed.
serverWrap: a netWorkSpaces server object. Reuse an existing server connection, instead of creating a new server connection.

cookieProtocol: Currently not used.
server: Object of class "nwsServer" representation of the server that this netWorkSpace connects to.
wsName: Object of class "character" representation of this netWorkSpace's name.
