Computes the standard deviation of the values of \code{x}.
}
\usage{
std(x, flag=0)
}
\arguments{
\item{x}{numeric vector or matrix}
\item{flag}{numeric scalar. If \code{0}, selects unbiased algorithm.
If \code{1}, selects biased algorithm (currently unsupported).}
}
\details{
Simply invokes \code{\link[stats]{sd}}.
}
\value{
Return value depends on argument \code{x}. If vector, returns the
standard deviation. If matrix, returns vector containing the
standard deviation of each column.
