私はHadley Wickham's guide to create packagesに従おうとしていますが、手順を正確に実行した後にエラーが発生しています。私は他の多くの人が間違いなくそうすることができたことを知っているので、私はどのように進むべきか不明です。ここで私のdevtoolsにhas_devel（）関数がないのはなぜですか？
は、これまで私の入力と出力です：

すべてはここまでうまくいっているようだが、ここで分解します。

Iはhas_devel機能を使用できるように、私は何を変更すべきです？
私は同じ問題がありました。 https://github.com/hadley/devtools/issues/1219を参照して、まず 'find_rtools（）'を実行してください。 –
