catboost.save_pool {catboost} | R Documentation

## Save the dataset

### Description

Save the dataset to the CatBoost format. Files with the following data are created:

- Dataset description

- Column descriptions

Use the catboost.load_pool function to read the resulting files. These files can also be used in the Command-line version and the Python library.

### Usage

    catboost.save_pool(
      data,
      label = NULL,
      weight = NULL,
      baseline = NULL,
      pool_path = "data.pool",
      cd_path = "cd.pool"
    )

### Arguments

`data` | A data.frame with features. The following column types are supported: double factor. It is assumed that categorical features are given in this type of columns. A standard CatBoost processing procedure is applied to this type of columns: 1. The values are converted to strings. 2. The ConvertCatFeatureToFloat function is applied to the resulting string. Default value: Required argument
`label` | The label vector.
`weight` | The weights of the label vector.
`baseline` | Vector of initial (raw) values of the label function for the object. Used in the calculation of final values of trees.
`pool_path` | The path to the output file that contains the dataset description.
`cd_path` | The path to the output file that contains the column descriptions.

### Value
