Note: since nrow and ncol internally use dim, they can also be directly used with an lgb.Dataset object.

Examples

data(agaricus.train, package = "lightgbm") train <- agaricus.train dtrain <- lgb.Dataset(train$data, label = train$label) stopifnot(nrow(dtrain) == nrow(train$data)) stopifnot(ncol(dtrain) == ncol(train$data)) stopifnot(all(dim(dtrain) == dim(train$data)))
