Create a remote R session — dsSession,OpalConnection-method • DSOpal

Create a remote R session if none exists. If a remote R session already exists, it will be reused. Returns an object of class OpalSession-class representing the remote R session accessible through this connection.

Usage

# S4 method for class 'OpalConnection'
dsSession(conn, async = TRUE)

Arguments

conn: An object that inherits from OpalConnection-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.

Value

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

Examples

if (FALSE) { # \dontrun{
con <- dsConnect(DSOpal::Opal(), "server1",
  username = "dsuser", password = "password", url = "https://opal-demo.obiba.org")
session <- dsSession(con, async=TRUE)
dsDisconnect(con)
} # }
