| \title{Names of Slots Inherited From a Super Class} |
| \description{ |
| For a class (or class definition, see \code{\link{getClass}} and |
| the description of class \code{\linkS4class{classRepresentation}}), |
| give the names which are inherited from \dQuote{above}, i.e., super |
| classes, rather than by this class' definition itself. |
| } |
| \usage{ |
| inheritedSlotNames(Class, where = topenv(parent.frame())) |
| } |
| \arguments{ |
| \item{Class}{character string or |
| \code{\linkS4class{classRepresentation}}, i.e., resulting from |
| \code{\link{getClass}}.} |
| \item{where}{environment, to be passed further to |
| \code{\link{isClass}} and \code{\link{getClass}}.} |
| } |
| \value{ |
| character vector of slot names, or \code{\link{NULL}}. |
| } |
| \seealso{ |
| \code{\link{slotNames}}, \code{\link{slot}}, \code{\link{setClass}}, etc. |
