\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}.}
