R: Accessors for model parameters.

xgb.parameters<- {xgboost} | R Documentation

## Accessors for model parameters.

### Description

Only the setter for xgboost parameters is currently implemented.

### Usage

    xgb.parameters(object) <- value

### Arguments

`object` | Object of class `xgb.Booster` or `xgb.Booster.handle`.
`value` | a list (or an object coercible to a list) with the names of parameters to set and the elements corresponding to parameter values.

### Details

Note that the setter would usually work more efficiently for `xgb.Booster.handle` than for `xgb.Booster`, since only just a handle would need to be copied.

### Examples

    data(agaricus.train, package='xgboost')
    train <- agaricus.train

    bst <- xgboost(data = train$data, label = train$label, max_depth = 2,
                   eta = 1, nthread = 2, nrounds = 2, objective = "binary:logistic")

    xgb.parameters(bst) <- list(eta = 0.1)
