ネストされたリストをラップするのに問題があります。リストの 1 つの要素のサンプルの構造を次に示します。
$ F01 :List of 7
..$ 0:'data.frame': 16 obs. of 3 variables:
.. ..$ lengths: Factor w/ 8 levels "1","2","4","5",..: 1 2 3 4 5 6 7 8 1 2 ...
.. ..$ values : Factor w/ 2 levels "C","N": 1 1 1 1 1 1 1 1 2 2 ...
.. ..$ Freq : int [1:16] 1 2 0 1 1 1 1 0 1 3 ...
..$ 1:'data.frame': 20 obs. of 3 variables:
.. ..$ lengths: Factor w/ 10 levels "1","2","3","4",..: 1 2 3 4 5 6 7 8 9 10 ...
.. ..$ values : Factor w/ 2 levels "C","N": 1 1 1 1 1 1 1 1 1 1 ...
.. ..$ Freq : int [1:20] 0 1 1 1 1 0 1 0 1 1 ...
リストの 1 つの要素に関数を簡単に適用できますlapply: F01 と言う
lapply(data$F01,function(x) x[which(x[['values']]=="C"),])
次に、ネストされたリスト全体に次のように適用することを考えましたrapply。
rapply(data,function(x) x[which(x[['values']]=="C"),],how="list")
Error in `[[.default`(x, "values") : subscript out of bounds
rapply は非リスト要素 (この場合は data.frame) に再帰的にラップする必要があるため、この rapply エラーが発生する理由がわかりません。私が得られない明らかなことはありますか？
