そして、概要を把握し、ファイルを切り替える必要がないように、それらを1つのdata.frameまたはマトリックスにマージする必要があります。しかし、これを解決する問題は、単に使用するよりも少し難しいようdata.frameです。

行の長さが異なるという問題を回避する方法を知っている人はいますか？

 merge(as.data.frame(loss), as.data.frame(loh), by="row.names")

ただし、両方の行列に一致する行名がないため、空のデータフレームが表示されます。あなたもすることができます

 merge(as.data.frame(loss), as.data.frame(loh), by="row.names", all=TRUE)

複数のデータフレームの場合、関数Reduceを使用します。

 Reduce(merge, list(data1, ..., dataN)))

by引数もに渡すようにしてくださいmerge。
