複数の列を含むリストをデータフレームに変換する

Question

リストの各エンティティ内に複数の列を持つリストがあります。私はエンティティと同じ数の行を持つ別のデータフレームでこれをcbind（）したいので、2つの列を抽出して各エンティティを1つの行に変換する必要があります。ここで

は私のリストです：

だから私は基本的に、リスト内の各エンティティで3番目と4番目の列を呼び出し、データフレームで出力を持っていると思います。行の数はリストの各エンティティごとに異なるため、idとnameの2つの列を持つ新しいデータフレームで、各エンティティを独自の行に結合したいと考えています。

の目標は、このような最終的な出力の外観を持つことです。

Answer 1

我々はlapply

と list

do.call(rbind, lapply(lst, function(x) do.call(cbind, lapply(x[c('id', 'name')], toString))))
