 /**
  * Handles an R error with the most general argument signature. All other facade variants delegate
  * to this method.
  *
  * <p>Note that the method never actually returns a result, but the throws the error directly.
  * However, the signature has a return type of {@link RError} to allow callers to use the idiom
  * {@code throw error(...)} to indicate the control transfer. It is entirely possible that, due to
  * condition handlers, the error will not actually be thrown.
  *
  * @param node {@code RNode} of the code throwing the error, or {@link #NO_NODE} if not available.
  *     If {@code NO_NODE} an attempt will be made to identify the call context from the currently
  *     active frame.
  * @param msg a {@link Message} instance specifying the error
  * @param args arguments for format specifiers in the message string
