}
\arguments{
	\item{obj}{A \code{flowJoWorkspace}, \code{GatingSet}, or \code{GatingHierarchy}}
	\item{y}{can be omitted if \code{obj} is a \code{GatingHierarchy}. A \code{character}, or \code{numeric} if \code{obj} is a \code{GatingSet}. A \code{character} if \code{obj} is a \code{flowJoWorkspace}}
}
\details{
	Retrieve a list of keywords from a \code{flowJoWorkspace}, \code{GatingSet}, or \code{GatingHierarchy} for a particular sample. The sample is specified via \code{y}, either a numeric index into a \code{GatingSet}, or a sample name (\code{character}) for all other types of \code{obj}. 
}
\value{
	A list of keyword - value pairs.
