\title{Radial (Galbraith) Plots}
\description{
   The function \code{radial} is generic. It can be used to create radial (also called Galbraith) plots.
}
\usage{
radial(x, \dots)
galbraith(x, \dots)
}
\arguments{
   \item{x}{an object of class \code{"rma"}.}
   \item{\dots}{other arguments.}
}
\details{
   Currently, there is only a method for handling objects of class \code{"rma"} with the \code{radial} function. Accordingly, the corresponding method is called \code{\link{radial.rma}}. See the documentation for that function for more details.
