\title{Create Diagonal Matrix From Vector}
\description{
Given an input row or column vector, \code{vec2diag} returns a diagonal matrix with the input argument along the diagonal.
}
\usage{
vec2diag(x)
}
\arguments{
\item{x}{a row or column vector.}
}
\details{
Similar to the function \code{\link{diag}}, except that the input argument is always
treated as a vector of elements to place along the diagonal.
