\title{Circle distance function}
\usage{
mesh.dcircle(p, radius = 1, ...)
}
\arguments{
\item{p}{A matrix with 2 columns (3 in \code{mesh.dsphere}), each row
representing a point in the plane.}
\item{radius}{radius of circle}
\item{...}{additional arguments (not used)}
}
\value{
A vector of length \code{nrow(p)} containing the signed
distances to the circle
}
\description{
Signed distance from points \code{p} to boundary of circle to
allow easy definition of regions in \code{\link{distmesh2d}}.
