csvファイルから読み取られた(追加された)次のdata_frame構造があります。基本的に、これは各オペレーター (AMDLJ) のスコアが、Excellent、Good、Ok、Poor、Terrible のいずれであるかをまとめたものです。他のフィールド date と scorer (後で使用する予定ですが、現時点では必要ありません)。
私が苦労しているのは、このデータを棒グラフ (各演算子の合計数を除算して正規化) と棒グラフをプロットできる形式に縮小する方法です。このデータ フレームを次のようなものに縮小するにはどうすればよいですか。これにより、geom_bar を大きくすることができます。
Operator Score Count
A Good 11
A Poor 5
A Ok 3
A Terrible 0
A Excellent 0
D Good 36
D Poor 50
D Ok 10
D Terrible 1
D Excellent 0
オペレーターに従って初期データフレームをサブセット化し、要約から数値を取得できることを知っています
dfA = subset(df, Operator=='A')
summary(dfA)
しかし、このプロセスを自動化したいと思います（つまり、データフレームを上記の構造に自動的に再成形し、そこからggplot2を使用して結果を視覚化できます）。ただし、この問題をどこから始めればよいかわかりません
