\title{
Get the population proportions of a node (population) in a GatingHierarchy
}
\description{
Calculate the population proportion (events in the gate / events in the parent population) associated with a node in the \code{GatingHierarchy}.
}
\usage{
\S4method{getProp}{GatingHierarchy,character}(x, y)
}
\arguments{
  \item{x}{
A \code{GatingHierarchy} object.
}
  \item{y}{
\code{character}
 The name of the node. A list of nodes is accessible via \code{getNodes(x)}.
}
}
\details{
Returns the proportion of cells in the gate, relative to its parent.
}
\value{
Returns a population frequency \code{numeric}.
