For each object, a value of 1 indicates that the object has that attribute, and a value of 0 that it does not. In set membership terms, a 1 indicates that the object is a member of that set and a 0 that it is not. } \value{A data frame (see Details).} \keyword{misc} \author{Jim Lemon} \seealso{\link{makeIntersectList}} \examples{ ns<-sample(1:8,20,TRUE) objects<-0 for(i in 1:length(ns)) objects<-c(objects,rep(i,ns[i])) attributes<-"Z" for(i in 1:length(ns)) attributes<-c(attributes,sample(LETTERS[1:8],ns[i])) setdf<-data.frame(objects[-1],attributes[-1]) categoryReshape(setdf) }
