dsSession: Create a remote R session

Description

Create a remote R session if none exists. If a remote R session already exists, it will be reused. Returns a logical indicating if a remote R session exists accessible through this connection.

Usage

dsSession(conn, async = TRUE)

Value

An object of class DSSession-class representing the remote R session.

Arguments

conn

An object that inherits from DSConnection-class.

async

Whether the result of the call should be retrieved asynchronously. When TRUE (default) the calls are parallelized over the connections, when the connection supports that feature, with an extra overhead of requests.
