\item{formula}{Casting \link[stats]{formula}, 
see details for specifics.}

\item{value.var}{Name of column that stores values to be aggregated numerics.}

\item{as.factors}{If \code{TRUE}, treat all columns as factors, including}

\item{factor.nas}{If \code{TRUE}, treat factors with NAs as new levels. 
Otherwise, rows with NAs will receive zeroes in all columns for that factor.}

\item{drop.unused.levels}{Should factors have unused levels dropped?
Defaults to \code{TRUE}, in contrast to \code{model.matrix}}

\description{
Reimplementation of function that originally part of the R package
\code{Matrix.utils} before the package was 
\href{https://cran.r-project.org/web/packages/Matrix.utils/index.html}{
deprecated}. The only difference is that this version of \code{dMcast} does
not include an aggregation feature at the end.
