Usage

inheritedSlotNames(Class, where = topenv(parent.frame()))

Arguments

Class

character string or classRepresentation, i.e., resulting from getClass.

where

environment, to be passed further to isClass and getClass.

Value

character vector of slot names, or NULL.

Examples

.srch <- search()
library(stats4)
inheritedSlotNames("mle")

## Not run: 
if(require("Matrix")) {
  print( inheritedSlotNames("Matrix") ) # NULL
  ## whereas
  print( inheritedSlotNames("sparseMatrix") ) # --> Dim & Dimnames
  ##  i.e. inherited from "Matrix" class

  print( cl <- getClass("dgCMatrix") ) # six slots, etc

  print( inheritedSlotNames(cl) ) # *all* six slots are inherited
}
## detach package we've attached above:
for(n in rev(which(is.na(match(search(), .srch)))))
    detach(pos = n)

## End(Not run)
