Usage

invoke(jobj, method, ...)

invoke_static(sc, class, method, ...)

invoke_new(sc, class, ...)

jobj: An R object acting as a Java object reference (typically, a spark_jobj).
method: The name of the method to be invoked.
...: Optional arguments, currently unused.
sc: A spark_connection.
class: The name of the Java class whose methods should be invoked.

Use each of these functions in the following scenarios:

`invoke`	Execute a method on a Java object reference (typically, a `spark_jobj`).	`invoke_static`
Execute a static method associated with a Java class.	`invoke_new`	Invoke a constructor associated with a Java class.
