Я пытаюсь отобразить список под названием TrainTestData, внутри списка есть ряд других списков, один из которых называется C Farolillo. Внутри этого списка у меня есть данные о поездах и тестах.
Список выглядит следующим образом:
Я пытаюсь нанести на картусписки для создания нового типа матрицы.
dtrain <- map(TrainTestData, ~map2(
X_train, Y_train, ~ xgb.DMatrix(data = .x, label = .y, missing = "NaN")
))
Я получаю следующую ошибку:
Ошибка в map2 (X_train, Y_train, ~ xgb.DMatrix (data = .x, label = .y, missing = "NaN")): объект 'X_train' не найден
Где я иду не так? Я пробовал несколько вариантов приведенного выше кода и не могу заставить что-либо работать.
Следующее выдает ту же ошибку:
dtrain <- map(TrainTestData$`C Farolillo`, ~map2(
X_train, Y_train, ~ xgb.DMatrix(data = .x, label = .y, missing = "NaN")
))
Проблема в том, что у меня есть списки внутри X_train lists?
> class(TrainTestData)
[1] "list"
> class(TrainTestData$`C Farolillo`)
[1] "list"
> class(TrainTestData$`C Farolillo`$X_train)
[1] "list"
> class(TrainTestData$`C Farolillo`$X_train[[1]])
[1] "matrix"
Примечание: я не могу предоставить пример кода, так как данные слишком велики.
Редактировать: Я могу создавать матрицы, используя:
xgb.DMatrix(data = TrainTestData$`C Farolillo`$X_train[[1]], label = TrainTestData$`C Farolillo`$Y_train[[1]], missing = "NaN")
Для 3-х матриц внутри X_train и Y_train дают:
> xgb.DMatrix(data = TrainTestData$`C Farolillo`$X_train[[1]], label = TrainTestData$`C Farolillo`$Y_train[[1]], missing = "NaN")
xgb.DMatrix dim: 2190 x 4 info: label colnames: yes
> xgb.DMatrix(data = TrainTestData$`C Farolillo`$X_train[[2]], label = TrainTestData$`C Farolillo`$Y_train[[2]], missing = "NaN")
xgb.DMatrix dim: 2190 x 4 info: label colnames: yes
> xgb.DMatrix(data = TrainTestData$`C Farolillo`$X_train[[3]], label = TrainTestData$`C Farolillo`$Y_train[[3]], missing = "NaN")
xgb.DMatrix dim: 2190 x 4 info: label colnames: yes
