\title{Contruct xgb.DMatrix object}
\usage{
xgb.DMatrix(data, info = list(), missing = NA, ...)
}
\arguments{
\item{data}{a \code{matrix} object, a \code{dgCMatrix} object or a character
indicating the data file.}

\item{info}{a list of information of the xgb.DMatrix object}

\item{missing}{Missing is only used when input is dense matrix, pick a float
value that represents missing value. Sometime a data use 0 or other extreme value to represents missing values.}

\item{...}{other information to pass to \code{info}.}
}
\description{
Contruct xgb.DMatrix object from dense matrix, sparse matrix or local file.

dtrain <- xgb.DMatrix(train$data, label=train$label)
xgb.DMatrix.save(dtrain, 'xgb.DMatrix.data')
dtrain <- xgb.DMatrix('xgb.DMatrix.data')
