Usage

## S3 method for class 'WrappedModel'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'H2ORegressionModel'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'H2OBinomialModel'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'H2OMultinomialModel'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'scikitlearn_model'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'keras'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'LearnerRegr'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'LearnerClassif'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'GraphLearner'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'xgb.Booster'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'workflow'
model_info(model, is_multiclass = FALSE, ...)

## S3 method for class 'model_stack'
model_info(model, is_multiclass = FALSE, ...)

Arguments
