\title{Calculates the difference between each element of a row (column) of a
matrix-like object}
\usage{
\S4method{colDiffs}{dgCMatrix}(x, rows = NULL, cols = NULL, lag = 1L, differences = 1L)

\S4method{rowDiffs}{dgCMatrix}(x, rows = NULL, cols = NULL, lag = 1L, differences = 1L)
}
\arguments{
\item{x}{An NxK matrix-like object.}

\item{rows}{A \code{\link{vector}} indicating the subset of rows
(and/or columns) to operate over. If \code{\link{NULL}}, no subsetting is
done.}

\item{cols}{A \code{\link{vector}} indicating the subset of rows
(and/or columns) to operate over. If \code{\link{NULL}}, no subsetting is
done.}

\item{lag}{An integer specifying the lag.}

\item{differences}{An integer specifying the order of difference.}
}
\value{
(row) less than x: \eqn{Nx(K-1)} or \eqn{(N-1)xK}.
