皆さんが私を助けてくれることを願っています。
私は2つのデータフレームを持つリストを持っています - データフレームcontestsでは、各行は最初の列が試合の勝者であり、2番目の列が試合の敗者である試合です。データ フレームには、プレーヤー固有の予測変数があります。これらはすべて数字です。BradleyTerry2 パッケージを使用してデータを分析しようとしています。私が使用しているコードは次のとおりです。expvar.contestsexpvar
a <- data.frame(read.csv(file.choose()))
b <- data.frame(read.csv(file.choose()))
ablist <- list(contests=a, expvar=b)
Model <- BTm(1, winner, loser, ~level2[..]+(1|..), data=ablist)
これは私が得るエラーです:
Error in Diff(player1, player2, formula, id, data, separate.ability, refcat, :
'player1$..' and 'player2$..' must be factors with the same levels
私の質問は、私が間違っていることは何ですか? いろいろ試しましたが、このエラーの意味がわかりません。変数を因子に変更する必要がありますか? なぜ、どのように？勝者と敗者はすべて同じカテゴリの予測変数を持っています。
ここに私の出力がありますdput(a)
