updateSelectInput()またはupdateSelectizeInput()を使用して、一連の入力に基づいて反応性データセットのサブセット化、サブセット解除の方法を理解するのが難しいです。私はユーザーが特定の順序で選択入力から選択肢のいずれかを選択できるようにしようとしています。次に、反応データセットの値に基づいて入力を2番目、3番目、4番目、5番目などで選択できるオプションを更新します更新されたデータテーブルを表示します。私はボート、国、港、日付に関するデータを扱っています。私は掘り下げたい機能を得ることができますが、オプションを選択解除しても入力の選択肢はリセットされません。私はfakeデータで再現可能な例を作るために数時間を費やしました。 Rマークダウン文書をコピーして貼り付けることで、私の例を実行できるはずです。コードは私のGitHubからデータを引き出します。誰かがこの問題を以前に持っていて、私を助けてくれることを願っています。私はあなたの考えを聞くのが大好きです。ありがとう、ネイトSelectInputがShinyのupdateSelectInputでリセットされない
