rowSds: Standard deviation estimates for each row (column) in a matrix

Description

Standard deviation estimates for each row (column) in a matrix.

Usage

rowSds(x, ...)
 colSds(x, ...)
 rowMads(x, center=NULL, constant=1.4826, na.rm=FALSE, dim.=dim(x), centers=NULL, ...)

Arguments

x

A numeric NxK matrix.

center

A optional numeric vector of length N (K) with centers. By default, they are calculated using rowMedians<
