\title{Rank Correlation Test for Funnel Plot Asymmetry}
\description{
   The function \code{ranktest} is generic. It can be used to carry out the rank correlation test for funnel plot asymmetry as described by Begg and Mazumdar (1994).
}
\usage{
ranktest(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{ranktest} function. Accordingly, the corresponding method is called \code{\link{ranktest.rma}}. See the documentation for that function for more details.
