\usage{
xgb.config(object)

xgb.config(object) <- value
}
\arguments{
\item{object}{Object of class \code{xgb.Booster}. \bold{Will be modified in-place} when assigning to it.}

\item{value}{An R list.}
}
\value{
\code{xgb.config} will return the parameters as an R list.
}
\description{
Accessors for model parameters as JSON string
}
\details{
Note that assignment is performed in-place on the booster C object, which unlike assignment
of R attributes, doesn't follow typical copy-on-write semantics for assignment - i.e. all references
to the same booster will also get updated.

See \link{xgb.copy.Booster} for an example of this behavior.
