 \title{Calculates the standard deviation of the difference between each element of
 a row (column) of a matrix-like object}

 \usage{

 \S4method{colSdDiffs}{dgCMatrix}(x, rows = NULL, cols = NULL, na.rm = FALSE, diff = 1L, trim = 0)

 \S4method{rowSdDiffs}{dgCMatrix}(x, rows = NULL, cols = NULL, na.rm = FALSE, diff = 1L, trim = 0)

 }
 \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{na.rm}{If \code{\link[base:logical]{TRUE}}, \code{\link{NA}}s

 are excluded first, otherwise not.}
 
 \item{diff}{An integer specifying the order of difference.}
 

 \item{trim}{A double in [0,1/2] specifying the fraction of observations to
 be trimmed from each end of (sorted) x before estimation.}

 }
 \value{

 Returns a \code{\link{numeric}} \code{\link{vector}} of length N (K).

 \description{

 Calculates the standard deviation of the difference between each element of
 a row (column) of a matrix-like object.

 The S4 methods for \code{x} of type \code{\link{matrix}},
 \code{\link{array}}, or \code{\link{numeric}} call

 \code{matrixStats::rowSdDiffs}
 / \code{matrixStats::colSdDiffs}.
