xgb.parameters<-

0th

Percentile

Accessors for model parameters.

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.
