Bluemix DashDB サービスで R スクリプト機能を使用しています。プロットを生成し、dashdb コンソール (Bluemix ダッシュボードから起動) でデータを視覚化できます。この R スクリプトを呼び出して結果を使用する外部コードを作成するにはどうすればよいでしょうか。
サービスは NodeRED アプリケーションにバインドされています。「http」ノードを使用してリクエストを処理し、基礎となる dashdb サービスで R スクリプトを呼び出し、結果のプロットを結果として提供するフローを何らかの方法で作成することは素晴らしいことです。出来ますか？
dashdb Web コンソール/ダッシュボードを使用する以外に R スクリプトを実行する方法はありますか? ありがとう
